What’s new 2011




Elites of my birth place

Azar-Andish, a social periodical that is published in my birth place Maragheh and distributed locally has recently released short news about me under the column entitled ‘Elites of Maragheh.’ Some remarkable facts is stated about me however some points are exaggerated. Although I left Maragheh when I was 19, I always have loved my birth place and it has been a pleasure for me to be of benefit for my birth place.



Caged bird 

It is on fourth day of December mid-morning that his mobile phone on the work desk of his cell-office rings. He immediately looks at the small monitor of phone set to see who is calling and he reads the word “unknown”!? Without hesitation he guesses from who it should be. He opens the phone set and hears the voice of a man who tells, ‘Hello, Mr. Ala.., oh sorry, Mr. Ta..’.

He replies, ‘Yes, this is me.’

‘How are you?’ he hears from the caller.

‘I am fine, thanks’, he answers.

The caller says, ‘I wanted to meet you to talk about your travel to Cape Town, South Africa’.

‘But I have never traveled to South Africa’, he replies.

The caller says, ‘Then we can talk about your other travels. Next week I will talk to you to fix an appointment, bye.’

The phone conversation is finished but the load of questions again comes to his mind. He is not unfamiliar with such the calls. What happened again? What is the meaning of this call? It is surprising, the intelligent officer is not aware that I have not traveled to South Africa. ‘But wherefrom has he informed about the plan for my travel to South Africa?’ he interrogates himself. Very many questions in his mind and a deep anxiousness once again. It is for the 20th time that he is summoned/contacted by the intelligent agents since August 2008 as soon as the current minister of communications, then the president of space agency, took over. As the son of the biggest usurer of his hometown, he was occupying the position of the presidency of the space agency of the Myth-land before being appointed as the minister. It was an overwhelming agony and regret that a person with such a negative personality became a minister. But it was there and one could guess what would happen following this appointment. This evil take over switched on the aggression of the intelligent agents to Ta… since then.  …



I watch an interesting and informative program being broadcasted by one of the outstanding satellite TV channels about NASA’s Mars Science Laboratory (MSL), which includes the car-sized rover known as Curiosity. The manager of this project, Dr. Firouz Naderi is interviewed in the program talking about his activity and contribution to the MSL project and also his background and past. The impressing and regretting point about his past as he explains is that how after getting back to his native country following graduation as a Ph.D. in electrical engineering from the University of Southern California the authorities of the new-coming revolutionary government fired him from the Iranian Remote Sensing Center of the date wherein he was working and its headquarters situated in the Mahdasht Satellite Receiving Station. The old and primitive employees of the Iranian Remote Sensing Center recall him quite well and talk about good memories with Naderi. The Mahdasht Satellite Receiving Station was one of the five important receiving stations all around the world with the mission to receive earth space data from United States Landsat. After leaving his native land Naderi joined NASA’s Jet Propulsion Laboratory (JPL) and took important and considerable responsibilities and functions. He is now an outstanding space scientist and engineer that serves to the humanity and all of the people in the globe. Rejecting, firing, banishing, putting under discrimination and pressure are all the reward for genuine and competent people of the Myth-land since when it has been ruled by the empire of dissimulation.


Winter in mid-fall

On November 8 and 9 there is an unforeseen and relatively heavy snowfall around home and workplace of mine. It is actually the same for almost northern part of the country. The temperature fall-down is much. The schools were announced closed by the authorities and on Wednesday I faced difficulty in reaching my workplace at the remote Mahdasht Receiving Station that is not so far from home. Banishing me to the Mahdasht Receiving Station since four years ago in mid-2007 has been beneficial for me from the viewpoint of providing me with enough time and opportunity as well as proper and relatively safe and free of obtrusiveness environment for research and advancing my broad effort for developing microwave remote sensing with particular focus on synthetic aperture radar interferometry (InSAR) technique, the opportunity which in the recent decades has been available in none of the Iranian academic and research centers. I believe that such the thing has been a need for me particularly after reaching the accomplishment of being a Doctor of Philosophy in Physics in 2008. As a piece of the Myth-land, my organization looks like an occupied territory ruled by its greatest wicked, malevolent and immoral foes. It has led to a situation that for being honest, clean and safe in this era one should bear a very dreadful pressure, torture and suffer very horribly without any shelter and support. Under the empire of dissimulation I beside my family have been indeed facing much of agony, discrimination, limitation and loss caused by aforesaid circumstances. Being and living freeborn and noble is the priceless treasure that I have paid/am paying enormously for it!

Snow in mid-fall; my work place


Again East

Last days of my travel to China for attending APSCO’s Third International Symposium on Earth Quake Monitoring and Early Warning by Using Space Technology jointly organized by the Asia-Pacific Space Cooperation Organization (APSCO) and the Ministry of Industry and Information Technology of China (MIIT) and held mid-September in  Beijing, China was interfering with another event in the Middle East; it was the ISNET (Inter-Islamic Network on Space Sciences and Technology)/Royal Jordanian Geographic Centre (RJGC) Workshop on Applications of Satellite Technology in Water Resources Management in Amman, Jordan scheduled for 18-22 September 2011. I was one of the provisioned participants of the Workshop but I had to withdraw attending it because of the partial interference of the time of two events.

Moreover, there were arrangements for my participation in the United Nations/International Astronautical Federation (IAF)/ European Space Agency (ESA) 21st International Workshop with the theme “Space for Human and Environmental Security” back to back to the 62nd International Astronautical Congress in Cape Town, South Africa. The workshop was scheduled for 30 September to 2 October and the congress from 3 to 7 October. Although it was looking promising at first but it misled to be fulfilled in the last days. Frustrated at the red tape and misrules I finally cancelled my travel to Cape Town at the last hours since I failed to receive the authorization of the Board for Monitoring the Travels of State Employees Abroad.  I therefore missed attending and contributing to both of the workshop and congress.

However, failed in attending IAC2011 and UN/IAF/ESA Workshop I traveled to Vietnam a week later to attend the United Nations/Vietnam Workshop on “Space Technology Applications for Socio-Economic Benefits” that was held from 10 to 14 October 2011 in Hanoi. It was a successful meeting that was held in the site of the Vietnam Academy of Science and Technology (VAST) with a specific architecture. During my stay in Hanoi the humidity was almost too high and most of the time unbearable. Hanoi that indeed should be called the city of motorbikes and lakes attracted me a lot and I am happy that I benefited the opportunity to be there for at least a week.

I started my travel to Hanoi via Bangkok on late Saturday evening, 8 October. The next day I left the Suvarnabhumi International Airport of Bangkok to the Noibai Airport of Hanoi and reached there in the afternoon. It was warm and the humidity was too high. Both Vietnam and Thailand are tropical countries. I am picked up by the agent of the workshop organizers and went to Trade Hotel. The hotel was old fashion. It was situated beside a nice lake looking very romantic and eye-catching.

On Monday 10 October I attended Vietnam Academy of Science and Technology (VAST) the venue for the United Nations/Vietnam Workshop on Space Technology Applications for Socio-Economic Benefits. I accompanying other participants went from hotel to VAST by bus. with a population of 6.5 million Hanoi seemed to be very crowded city. It is called the city of motorbikes and lakes.

At VAST the meeting was opened by the organizers. They presented keynotes and then the technical presentations were given in the morning and afternoon sessions. I had a busy day. Late in the evening all the participants attended Culinary Culture Sen Park West Lake in Hanoi for dinner banquet  hosted by the organizers. It is very interesting and memorable. I enjoy it too much.

In the afternoon of the second day of the workshop I gave my presentation entitled “New Satellite Technologies in the Service of Socio-Economic Benefits and Bridging the Gaps for Sustainable Development”. It was about my work on SAR Interferometry technique in recent years with a focus on socio-economic benefits that it provides. It was well received by the representatives from UK and USA. I later took the responsibility of the rapporteur of the next session. In the evening it was raining severely.

In the third day of the workshop in the afternoon I attended the hands-on training organized by Esri Vietnam and Thailand on geographic information systems (GIS) which continued in the next day by noon. Early at night I joined other colleagues to go to a shopping center but we failed to buy something. The prices was high. We then go to visit Mausoleum of Ho Chi Minh the outstanding champion of Vietnam who stood up before the aggression of USA to Vietnam about 45 years ago. There is a ceremony to respect him each day in the morning and evening.

On the fourth day of the workshop in the afternoon the workshop participants visited Hanoi University of Technology (HUT). We later went to sightseeing in Hanoi and visited to the Old University of Hanoi. It is interesting and wonderful. In Vietnam the turtle is the symbol of tolerance and wisdom. It is seen clearly in the architecture of the Old University. Early at night I joined other colleagues to go to visit the city and after having dinner at a restaurant beside lake and walking around get back hotel.

On Friday 14 October I attended the last day sessions of the workshop. I also joined other people to discuss the plans of the working group on environmental monitoring. The workshop ended mid-day. In the afternoon I joined other colleagues to go for sightseeing. On Saturday 15 October I left the hotel mid-day. In the afternoon I left  Hanoi Airport to Bangkok. I arrived there after one and half hours. I waited at the Bangkok Airport by late at night when the plane flew to Tehran but before that we flew to Pattaya for fueling the plane. It took about 25 minutes to reach Pattaya and an hour for fueling the airplane. It was strange that the plane did not fuel in Bangkok Airport and was obliged to go to Pattaya that was another city of Thailand. It did not seem to be normal. Anyway we left Pattaya mid-night and headed to Tehran. Almost all the passengers of the plane were tourists and business people like the case of China to where I traveled about a month ago. The plane landed in Imam Khomeini Airport early in the morning on Sunday 16 October and my travel to Vietnam finished after a week. It was my third travel to the East after Pakistan and China in current year 2011. I found the vietnamese very honest, conscientious and deserving respect.

Journey to China

 In the Iranian myth, Kay Kāvus flew up to heaven using propulsion by hungry eagles, as described by Ferdowsi, one of the world’s greatest epic poets, in his magnificent work Shah-Nameh. Kay Kāvus, as it is said, was indeed dreaming to reach China that was the farthest civilized land and Empire at that time. Nowadays in the age when the physical separation between the civilizations is actually removed thanks to the developments and progression of different technologies such as communications, transportation and so on, exploring different cultures and civilizations is emerging as wonderful and fantastic experience and adventure for larger group of people. One of my greatest dreams was always traveling to China and seeing there closely. Few efforts for realizing this dream misled to success but finally I was lucky to fulfill it last September. I traveled to China mainly to attend the APSCO’s (Asia-Pacific Space Cooperation Organization) Third International Symposium on Earth Quake Monitoring and Early Warning by Using Space Technology that was held from on 13-15 September 2011 in Beijing.

On 10 September in the afternoon I left home to the Imam Khomeini Airport in south of Tehran to travel to China while I received my travel documents only an hour before leaving home to the airport without any subsistence allowance; it is hard to travel abroad in such the way. Poor official logistics is the common procedure in recent years; it is frustrating actually. When I reached the airport I was informed about the two-hour delay for my Iran Air flight. I took in the plane at about 9 o’clock at night but the plane did not take off due to some slight and ‘some technical problems’ according to the pilot. It was too hot inside the plane although I was a business class passenger and my seat inside the plane was comfortable and spacious. Almost all the passengers of this flight were travelling to China for business and touring. I was in a minority since these days the people like me who travels to China for a scientific purpose are rare. A passenger was brawling since he had left his coat in the waiting hall of the airport!? He wanted his coat and when the flight staff promised him that he would receive his coat from the office for lost stuff when he returns, he relieved and became quiet. Minutes later a number of middle age and young men and women requested the flight staff to allow them to get off. They were crying and looking unhappy. It was revealed that they have received the bad news of the demise of their close relative through their mobile phone. But they had their luggage in the cargo section of the plane and it took nearly three-quarters of an hour for finding and unloading their luggage. Finally at about 11 o’clock at night the plane left the airport for the 6.5-hour flight to China.

Next day the plane landed in the Beijing Capital Airport with about 3.5-hour delay. I was picked up by a driver from APSCO who took me to the Beijing Friendship Hotel, the biggest garden hotel in Asia. The hotel consisted of different buildings. I was accommodated in the room number 40512 of the building number 4. The view from the windows of my room was too nice and dreamy. I had my lunch at the Coffee shop of the Friendship Palace.

The meal was too spicy and I was indeed unfamiliar with Chinese style eating of food using the sticks. Having my dinner at the Coffee shop of the Friendship Palace I tried to adopt myself with the foods served at the Coffee shop. I found the served cold fish and beef very tasty. Walking around after dinner I felt surprised about the way of life of the people in Beijing. The city looked modern but I also saw the poorness and indigence of the people. It was unbearable and made me sad and distressed.

It was holiday on my second day of stay in Beijing. I had my lunch at the Juxiuyuan Restaurant near the Coffee Shop. Afternoon I went to the market opposite to the hotel on the other side of the Zhongguancun South Street. The mall was full of different goods.

On Tuesday 13 September APSCO’s Third International Symposium on Earth Quake Monitoring and Early Warning by Using Space Technology was started in the Building number one of the Friendship Hotel. Statements were given by the secretary of the symposium, the representative of the China’s Ministry of Industry and Information Technology (MIIT) and the Secretary General of APSCO, Dr. Zhang Wei. The inauguration ceremony was followed by the first technical session of the symposium focusing on the organizational aspects.

The second session started in the afternoon with my chairmanship. Its title was Earthquake Monitoring and Early Warning Theory and Technology. I gave also my presentation at the outset with the title “Early Warning and Earthquake Monitoring Using New Earth Observation Radar Techniques”. It was a sensitive experience for me and I felt that I do it very successfully although as I was advised the participants were almost unfamiliar with the subject of SAR Interferometry technique.

In the evening of the same day I joined other participants of the symposium to attend the banquet reception hosted by the Secretary General of APSCO. The banquet concluded soon.

The symposium lasted three days. In the last day on Thursday there was a round table session in the afternoon in which some suggestions and comments was given by the participants of the symposium. After the session the participants of the symposium went to visit the China Earthquake Network Center (CENC). It did not take long and there were only oral presentations by the head and deputy of the center and a short visit to the lab of the center.

Because of the heavy rainfall the plan for visiting Great Wall of China on Friday 16 September was cancelled, and instead I joined some of the participants of the symposium to visit the Hongqiao Pearl Market and shopping.

Traffic jam of Beijing was considerable and boring while it was being recompensed by the vastness, greenness and cleanness of the streets. I found Beijing an amazing place with large number of population that is about 22 million. The way they live and work is a considerable point that worth to know about it. Beijing is an alive and active entity deserving to be praised. On Sunday 18 September I left Beijing mid-day by plane with a one and half an hour delay. I nevertheless failed to see Great wall closely. I feel that I will return China very soon and I hope that I will be able then to visit Great Wall closely. I only enjoyed looking at the Great Wall synoptically from the height of about 3000m when I was leaving Beijing by plane in the mid-morning on September 18. It was also wonderful and very nice.

Magnificent and incredible

It was early June this year that the idea of my travel to Pakistan brought forth. At first it seemed a bit hard and somewhat impossible. However the arrangements went on orderly and from 10 to 17 July I traveled there to attend the Expert Meeting for Development of Data Sharing Platform and Technical Experience-sharing for Cost-effective Operation and Maintenance of National Satellite Earth Stations. The meeting jointly organized by the Islamic Network on Space Sciences and Technology (ISNET), OIC Standing Committee for Scientific and Technological Cooperation (COMSTECH) and Islamic Educational, Scientific and Cultural Organization (ISESCO) to be held on 12–15 July 2011 in Islamabad the capital of Pakistan.

While it was too warm, I left the Imam Khomeini International Airport south of Tehran to Abu Dhabi by Etihad Airways accompanying two colleagues from the Iranian Space Agency. Early at night we landed in Abu Dhabi Airport located in the United Arab Emirates (UAE). We had to wait about three hours to leave Abu Dhabi to Islamabad, Pakistan. 

Early in morning on Monday at the Islamabad Benazir Bhutto International Airport we were picked up by the COMSTECH representative and went to COMSTECH Hostel in Islamabad’s official region. At 4 o’clock in the morning it was too warm and everywhere was under the control of security forces and police. Early in the morning through the only windows of my room at COMSTECH Hostel I was able to see the Prime Minister Secretariat building and part of Islamabad. It was green everywhere and also hot in this time of the year due to monsoon season that begins from July and lasts by October each year there.

The meeting opened on 12 July with the remarks of the COMSTECH, ISESCO and ISNET top authorities. The second session of the meeting began with my presentation entitled, “ISA’s Data Sharing and Ground Receiving Station Developments.”

 I give my presentation to the Expert Meeting in the first day of meeting 

In the evening I attended the dinner banquet hosted by the president of Pakistan Space and Upper Atmosphere Research Commission (SUPARCO), H. E. Mr. Ahmad Bilal. He received us at the Islamabad Marriot Hotel. We went there under security control. The hotel’s environment was nice and we were accommodated in a not so large hall with traditional decoration and eastern privacy. There we benefited the opportunity to enjoy the Pakistani folk music.

SUPARCO is Pakistan’s national space agency that was established in 1961 as a Committee and was granted the status of a Commission in 1981. It is mandated to conduct Research and Development in space science, space technology, and their peaceful applications in the country. It works towards developing indigenous capabilities in space technology and promoting space applications for socio-economic uplift of Pakistan. SUPARCO hosts the ISNET Secretariat in Karachi.

In the second day of the meeting I was the chairman of two sessions of the meeting. After the meeting in the afternoon I joined other international guests as well as ISNET staff to go to the city market again under the security control.

The morning session of the third day was a session for discussing the issue of cooperation. I made few comments and suggestions. In the afternoon I joined other participants to visit the SUPARCO’s Ground Receiving Station 45km off the Islamabad metropolitan. We went there under the security control. Islamabad looks to be a nice and green area thanks to the monsoon currents. We visited the station and then the Institute of Space Technology that basically is concentrated on aerospace technology.

 Group photo in front of the Pakistan Monument Museum

In the evening we go to visit the Monument Museum which I found it too nice and magnificent. We later visited the symbol of Pakistan opposite to the museum. After buying spice we drove to an outdoor restaurant in the Paradise area of Islamabad. Mr. Arshad Siraj, the Executive Director of ISNET received us there.

 Closing session of the Expert Meeting 

The morning session in the last day of the meeting was a session for discussing the recommendations of the meeting. I made few comments and suggestions. In the closing ceremony of the meeting the representatives of COMSTECH, ISESCO and ISNET were present. After lunch I joined other participants to go to the Feisal Mosque for Friday Prayer. It is a big mosque in north of Islamabad. It was unbearably warm and the humidity was too high. In the evening we went to the Margallah Hills National Park in north of Islamabad. It was a wonderful and nice place. We enjoyed looking at the city of Islamabad with the population of 1.2 million from that high area. We later went to the Monal Restaurant that was a magnificent and dreamy place. While we were warmly received by Mr. Arshad Siraj, we had our dinner there.

It was great pleasure and luck for me to visit Islamabad in course of the Meeting. I left Pakistan with the sense of happiness and satisfaction for attending the well-organized meeting as well as visiting the beautiful and charm capital city. All the people of ISNET particularly its Executive Director, Mr. Arshad Siraj, made the utmost hospitality, for which I am pride and happy. The memory of visiting and enjoying the beautiful Margallah Hills National Park and dreamy Monal Restaurant as well as the wonderful Pakistan Monument Museum will be never removed from my mind and I always would like to benefit the opportunity and bliss of visiting them in the future for several times.  



In continuation of the exploratory work of using Synthetic Aperture Radar Interferometry (InSAR) technique on aquatic bodies in different locations all around the globe the project C1P.8242 under the ESA affiliated European Space Research Institute (ESRIN) was started last February. ESRIN secures the needed data for the project. The background of this study and exploratory work goes back to October 2010 when I observed that using SAR Interferometry technique for aquatic bodies with the temporal baseline of maximum 16 seconds could show considerable results enabling us to estimate the direction of sea surface motion in larger extent, the change in the height of the sea surface in the direction of satellite sensor, the sea surface disturbance and whether the water motion is bulk and smooth or otherwise. The method has been examined for Haiti, western Chile and western Turkey coast areas however empirical field checkups is necessary and the job will be also continued for examining other sites around the world for which the relevant data is available. For this application of SAR Interferometry the title of Liqui-InSAR is proposed that refers to the use of SAR interferometry technique for liquid bodies in general that is distinguishable from the SAR Interferometry of solid bodies for which the expression of Solid-InSAR is proposed and that deals with the features like soil, sand, vegetation, rocks, snow and other cryospheric phenomena. The comments and discussion on the proposed idea by those who are interested in the subject is warmly welcomed. A report on the new results which we obtained for Liqui-InSAR application, is going to be made available soon. Two examples of the recent products for western Turkey are seen below.

Who are visiting this site?

In the five-month period beginning from 2 December 2010 to 2 May 2011 this weblog is visited 3,521 times (23.2 visits per day) by different visitors all around the world which distribution is seen in the map below with red spots.


The number of page views from 18 October 2010 ending to 2 May 2011 was 9,294 which were visited by different visitors from 112 countries. The first is the United States of America with 431 visitors which is followed by Iran, Great Britain, India, Canada and Italy with 190, 139, 136, 71 and 53 visitors respectively.


The table of the top post of my weblog in recent year is as follows while SAR Interferometry and space related topics grabbed more attention of the visitors.



Unfulfilling the promises

On Wednesday, April 27 the president of the agency accompanying a group of old and new colleagues come to Mahdasht Receiving Station. At first I think that the reason for his visit to Mahdasht is for Nowruz but it soon reveals that he is there to introduce a new in charge for Mahdasht station and introduce the change of the name of the Mahdasht satellite station to Alborz Space Center. There is not seen any sign of fulfilling the promises of the president he talked about in his last visit to the station about half a year earlier in November 23, 2010 (See New president, new promises).  In that visit he insisted on his appreciation to the scientists and was honored for my work and study on important topics. He assured me that he would honestly support me and my work. He even stressed that I have to be relieved on his promises and that he was fully different of the recent presidents of the agency.


House-cleaning at the space agency

Nowrouz house-cleaning is a Persian tradition that the people perform it believing that they should make their homes and hearts clean and clear for a new start and new life before the beginning of New Year. Following the annexation of the space agency of Iran to Iran’s Presidency Institution early last fall and takeover of the new president of the agency, it was expected that this house-cleaning for the agency be carried out too much earlier at least before the beginning of the new solar year in Iran on 21 March 2011.  However, the expected house-cleaning has just started only this mid-April albeit at glacial speed. Presence of the self-styled deputies, managers and entourage that all were appointed by the three earlier presidents of the agency, and the unfavorable organizational set-ups and relations that all were the inheritance from them did not allow one to feel relieved that the new president could be successful while the official behavior and intension of his deputies, managers and entourage were opposing what he planned to realize. The new president actually needed a basic staff house-cleaning in the managerial level at the agency and adjusting the visions in conformity with the realities. The agency is now passing a critical state while it is not clear how would be the new coming deputies and managers. There is no way but to wait patiently to see how he would accomplish.


Happy New Solar Year and Happy spring!  




Precise DEM by using SAR Interferometry technique  

In continuation of exploring the available data of Western Turkey a set of products acquired using SAR Interferometry technique. The following images are generated by combining the descending image pair of the single look complex images (SLCI) of the C-band Advanced Synthetic Aperture Radar (ASAR) image mode system of Envisat satellitefor Western Turkey acquired on 20 May 2010 with an 8 second time baseline and the virtual baseline of 42.94m. The geometry of the technique is also shown above right for better clarification.

New TV set for home 

On Monday 7 March we renew our home TV set after about twenty years. It is a 37” LED Samsung model C5550. This modern flat screen Light Emitting Diode TV system substituted our electron gun Pars TV system with curved screen.  






Battle of wills!?

In Iran internet is heavily filtered by the state since Monday 14 February 2011 when a demonstration in support of the Tunisian and Egyptian nations and the revolt in the Middle East in general was organized by the Iranians. This filtration aims barely censorship of knowledge instead of limitation of communications. It affects everybody in Iran regardless of the sort of the knowledge and data that is searched by the people. The government calls it as the battle of wills. But the question is the battle of whom against whom?




Project start-up C1P.8242

Not so long passes since the time in October 2010 when I observed that using SAR Interferometry technique for water bodies with the temporal baseline of greatest 16 seconds could show considerable results. See SAR Interferometry of water bodies and Using InSAR Technique for Water Bodies. I tried to look at it for different cases and different areas for which the relevant data were available to me. I tested the technique for Haiti, Chile and Turkey with promising results. However further investigation is needed and with this in mind reporting the results of my observations to the ESA affiliated European Space Research Institute (ESRIN) I requested for support of ESRIN in this connection that led to acceptance of my proposal for implementation. According to the ESRIN authorities this is a less explored subject. As the Principle Investigator I will carry out the study and conduct it benefiting the assistance of the colleagues selected for cooperation in this project. I also welcome assistance and cooperation of the interested people and organizations in this connection. I can be reached by clicking here.


Are they really extraterrestrial?

Some friend of mine, Mr. Shahbaz Goshtasebi, who is an engineer working in southern Iran, on 11 February 2011 shared with me the information about the unknown flying objects that have been emerging  recently at the sky of the Iranian southern cities in the Fars and Kerman Provinces including Rayen, Darestan of Bam, Shahdad, Sirach, Roudan and Minab.  Shahbaz reports that tens of those flying objects were seen at the sky of Boushehr in an afternoon. As a premier reflection, the authorities of the Hormozgan Province and the city of Boushehr related those flying objects to the United States of America. But after the diplomatic follow-ups for three days and accusing the existing foreign forces in the Persian Gulf for eventual monitoring of the Boushehr Nuclear installations, they unbelievably encountered the denial of the United States forces in the Persian Gulf and it was revealed that the United States troops have reported to the Pentagon about the observation of the unknown objects in the region that can be seen by the naked eye when flying only at the height of 50 to 100 feet from ground surface with no effect on the radar screens and advanced receivers of the United States warships.


Map of Southern Iran; the areas over which the flight of unknown objects is reported by the local witnesses are marked with red spots.

Presently a group of European and American scientists settled in Hormozgan Province and some other Persian Gulf Region countries are closely studying and investigating the matter. According to Shahbaz, it is probable that those flying objects have come to the Earth from a planet and have taken the samples of the living creatures on Earth, since in any area for which the observation of those flying objects is reported, there has been also the reports about the miss of the animals in the region and even a 16-year old villager man that is recorded by the Iranian local police. Using the mobile phone set camera a resident of the same village has recorded the event of flying of a pair of those unknown objects over the village. (Click here to see the video clip) This matter has not yet confirmed by the official authorities. According to the eye-witnesses the unknown objects fly silently and smoothly with few twinkling green and red lights and the antenna-like rods at the top and sides. Facing danger they fly rapidly towards the desert area at low height and disappear. It is said that the local police stations in the border and non-urban areas have been strictly prohibited of firing to those unknown flying objects.

COPUOS and Doomsday

In course of the 48th meeting of the Scientific and Technical Subcommittee of the Committee of Peaceful Uses of Outer Space (STS-COPUOS) that was held from 9 to 18 February 2011 in Vienna, Austria, on Thursday, 10 February a presentation with the title ‘Space Weather Super-Storm; Not IF but WHEN and Extreme Solar Minimum‘ was presented by L. Guhathakurta of USA. This presentation points to new concept that is emerging for discussion and elaboration in COPUOS. The concept of Doomsday is a delicate and sensitive one. Could we say that it is something like a natural disaster based on the interpretations that is given contemporarily? I believe that there is a great difference between the natural disasters and Doomsday notions. Natural disasters are incapable of making spiritual justice; the thing that based on our religious instructions Doomsday is the phenomena to comply it. All interested people are invited and welcome to share their comments, explanation and ideas in this connection with me.

Testing the SAR Interferometry technique for water bodies in Western Turkey

After examining the InSAR (Synthetic Aperture Radar Interferometry) technique for the water bodies of the Caribbean Haiti and Western Chile (see ‘Using InSAR Technique for Water Bodies; Parviz Tarikhi, October 8, 2010’, ‘SAR Interferometry of water bodies’, ‘A DEM with a temporal baseline of 8 seconds’, and ‘New research and study work on Haiti earthquake‘) for which the data acquired in January 2010 and early 2010 respectively, using the radar data provided by the European Space Research Institute (ESRIN) affiliated to the European Space Agency (ESA) I have carried out since early November 2010 investigation and research work on the available data which includes 756 single look complex images (SLCI) of the C-band Advanced Synthetic Aperture Radar (ASAR) image mode system of Envisat satellite in addition to other type of data. Such large number of data provides the possibility of frequent and large number of combinations which will lead to higher accuracy.

Like the past, in the case of Haiti and Chile, and more than ever before the results sound promising and the detailed stepwise study report is planned to be prepared as soon as the data investigation, and product generation work is developed sufficiently. Again, the results achieved by combining the available SAR image pairs of the area that are acquired successively with maximum 16 seconds of temporal baseline looks interesting and considerable for the water bodies that is the indication of the effectiveness of the technique.

For the Western Turkey study area the results of combination (amplitude-phase product only shown here) of 4 image pairs focusing on the water bodies are given below as can be located in the area map. The detail of the combination appears at the bottom of each product as image caption. The parallel baseline component (PBL) that plays the key role in producing interferograms is highlighted by red color. The temporal baseline component (TBL) is marked by green color. In each case the direction of the movement of the sea/lake water is distinguishable and the displacement in the direction of the line of sight is assessable. Knowing the direction of the motion of sea/lake water surface that is actually the indication of the movement of the water body and its long term trends could be useful for coastal zone management and the interaction of sea/lake water and coastal areas. Other potential benefits need to be further investigated and studied. It is further notable that by increasing the coverage area of the successive SAR images access to the information about the behavior of the sea/lake water movement in larger areas would be possible. This idea is in the process of examining and test for various cases and further different locations.

A foggy day around home

On Thursday 27  January a dense fog covers a wide area around home. It lasts for hours and creates beautiful landscapes. I record some with our digital camera. This natural phenomena is seen frequently in the area of our residence almost in cold seasons particularly winter.

Icy winter in exile

Mid-January this year we have a harsh and icy winter in Mahdasht. For several days everywhere around is freezed.

An old friend at our home

On Tuesday 4 January I and my family hosted my old friend Dr. Jamal I. Ismayilov and his wife at our home. They traveled to Iran in the first week of the New Year 2011 and we benefited this opportunity to meet. I know Jamal since 1997 when I traveled to Baku, Republic of Azerbaijan to attend the ESCAP/FAO/ESA sponsored Decision Makers Seminar on Space Information Technology Applications for Sustainable Agriculture Management, in Baku held on 13-17 October and hosted by the Azerbaijan National Air-Space Agency (ANASA). Jamal was the staff member of ANASA at that time working as a remote sensing expert.

 Dr. Jamal I. Ismayilov and his wife meet me and my family at our home in Karaj on Tuesday 4 January 2011. The photo shows Jamal (left) and I at home.  

I met Jamal in 2004 in course of the Inter-Islamic Network on Space Sciences and Technology (ISNET)/ Iranian Space Agency (ISA)/ Islamic Development Bank (IDB) International Workshop on Satellite Technology Applications in Communications and Remote Sensing in Tehran held on 9-15 October 2004 and the next year in course of the back to back events of the 11th Regional Working Group (RWG) Meeting on Remote Sensing, Geographic Information System and Satellite Based Positioning and the 10th  Regional Working Group Meeting on Meteorological Satellites Application and Hazard Monitoring in Isfahan held on 3-5 September 2005 followed by the 11th Intergovernmental Consultative Committee (ICC) Meeting on the Regional Space Applications Programme for Sustainable Development in Asia and the Pacific in Isfahan held on 6-7 September 2005. Jamal delegated the Repubilc of Azerbaijan for the meetings.

Jamal’s gift to me; the book Baku

In 2006 Jamal left ANASA and founded the private company INTEGRIS based in Baku with the main focus on the projects related to geographical information, remote sensing, and implementation of the digital photogrammetry technologies, preparation of digital map data, creation of corporative Geographical Information Systems (GIS), learning of natural and anthropogenic resources of practical and remote sensing data and applying these data in preparation of orthophoto and cadastre mapping through digital photogrammetry technologies. Since then he has been working in the position of the General Manager of INTEGRIS LLC.

    After reading your blog post I browsed your website a bit and noticed you aren’t ranking nearly as well in Google as you could be. I possess a handful of blogs myself and I think you should take a look here: http://dominateseowithwordpress.com You’ll find it’s a very nice tool that can bring you a lot more visitors. Keep up the quality posts

  8. Xavier Schiffert Says:

    I was wondering if you ever considered changing the page layout of your website? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having one or two pictures. Maybe you could space it out better?

    • Parviz Tarikhi Says:

      Thanks for your comment. I will try to improve it as you propose.

  9. Enid Bloczynski Says:

    I know this if off topic but I’m looking into starting my own weblog and was curious what all is required to get set up? I’m assuming having a blog like yours would cost a pretty penny? I’m not very internet savvy so I’m not 100% sure. Any recommendations or advice would be greatly appreciated. Cheers

    • Parviz Tarikhi Says:
