First of all, thanks to my supervisors Assoc. Prof. Dr. Elif Sertel, and Assist. Prof. Dr. Barat Mojaradi for inspiring me and for providing such an interesting project for me to work on. Thank you for your direction and your help in the development of my mind. Thank you for teaching me. I am honored to have worked with you and I have learned more from you than you know. I want to record my special thanks to Ahmad Alizade Govarching Ghale, Muhittin Karaman and Emre Ozelkan who always helped and encouraged me. I also wish to thank Istanbul Technical University (BAP), Turkey National Cultural Institution, Mr. Sharafattin Yilmaz and Mr. Ali Polat for their financial and emotional helps. I would also thank to the West Azerbaijan Environmental Protection Office, West Azerbaijan and East Azerbaijan Meteorological Offices and Artemia Research Center of Urmia University for their help. I would also to thank the Department of Geomatics Engineering and Research and Application Center for Satellite Communications and Remote Sensing (ITU-CSCRS) at the Istanbul Technical University for giving me the opportunity to come here and for providing an exciting and dynamic environment for me to mature as a scientist. Finally, I want to convey my thanks to my family for their support and encourage and understanding.
