SUPERVISOR Ms. Asma Shaheen Hashmi Assistant Professor Department of Earth Sciences University of Sargodha. iii ACKNOWLEDGMENT I am very grateful to Allah Almighty Who is the master of the Day of Judgment and the inventor of all mankind. There are no suitable words for His enormous sanctifications because He bestowed me the courage and boldness to complete my thesis work. I am also appreciative to my affectionate, caring and kind Parents and Husband to provide me full sustenance during my research work through all possible resources with great persistent. I owe the obligations of appreciation to Department of The Earth Sciences, which provided me this chance to complete my research in the emerging, evolving and developing field. I am grateful to the research supervisor, Asma Shaheen Hashmi for her great efforts, direction, appreciated recommendations and kind supervision made this possible. I am thankful to the Chairman of Earth Sciences Dr. Omer Riaz who provided me the chances to acquire imaginative skills and offering abilities for well preparation for my research. I would also like to thank the organizations such as PMD, Meteorological Department of Lahore for providing me the datasets of their meteorological stations. I am highly indebted to a web-source i.e www.meteoblue.com who works in cooperation with the University of Basel, Switzerland. They generate simulation- based data on NOAA/NCEP models. The meteoblue provided me statistical datasets of four meteorological stations free of cost. I highly appreciate their special support for research purpose. iv DEDICATIONS To Allah Almighty The Most Gracious and kind, To Prophet Hazrat Muhammad (PBUH) v Acronyms Notation Representation DIP Digital Image processing DEM Digital Elevation Model ETM Enhanced Thematic Mapper GIS Multispectral Scanning Band MSS Geographical Information system NASA National Aeronautics and Space Administration NDBI Normalized Difference Built -up NIR Near Infrared Rays PMD Pakistan Meteorological Department PCA Principal Component Analysis RS Remote Sensing SUPARCO Space and Upper Atmospheric Research Commission VIS Visible Infrared Band VPD Vapor pressure deficit WAPDA Water and Power Development Authority HKH Hindukush, Karakorum, Himalaya IPCC Intergovernmental Panel on Climatic Change ENSO El Nino or Southern Oscillation GHG Green House Gas vi CONTENTS Declaration Latter ii Certificates of Originality of Research Work iii Acknowledgement iv Dedication v Acronyms vi Contents vii List of Tables xii List of Figures xiii Abstract xvi CHAPTER: 1 INTERODUCTION 1 1.
