Mardin ilinde uzun yıllar yer yüzey sıcaklığı değişiminin incelenmesi

Yeryüzü arazi kullanımı ve arazi örtüsü diye ifade edilen birçok doğal (bitki örtüsü, su) ya da yapay (şehirler, yollar) nesnelerle örtülüdür. Yer Yüzeyi Sıcaklığı (YYS) ise yerin ışınsal cilt sıcaklığı olarak tanımlanır ve arazinin kullanım ve örtüsüyle doğrudan ilişkilidir çünkü sıcaklık maddelerin cinsine göre farklılaşabilmektedir. Dünyanın homojen bir yer yüzeyine sahip olmadığı gerçeği, YYS tespitinde farklı teknolojiler kullanılmasını sağlamıştır. Bu teknolojilerden biri termal algılamadır. Bugün, uydular yardımıyla termal kızılötesi kullanılarak düşük maliyetli, etkili ve hızlı bir şekilde YYS görüntüleri elde edilebilmektedir.  Ayrıca uyduların zamansal çözünürlüğü sayesinde istenilen bölge uzun süreli gözlenebilmektedir. Bu çalışmada Mardin şehrinde YYS’ nın uzun yıllar (29 yıllık) değişimi tespit edilmiştir.  

Investigation of long term land surface temperature changes in Mardin Province

The Land Surface Temperature (LST) is defined as the radiative skin temperature of ground and depends on the albedo, and whatever covers the surface such as natural surface of earth (vegetation, soil) or artificial elements (roads, buildings).  LST is a key parameter in many regional and global scale studies in urbanization, deforestation, greenness in urban areas, human health, and city planning.  Nowadays, the one of most suitable, cost effective, and rapid way to retrieve LST is to use remote sensing data, especially multispectral satellites data.  Remotely sensed data is a type of data that provides a long term synoptic view of continuous coverage of LST by recording the solar radiation that reflects from surface. The radiation at the earth's surface varies widely due to atmospheric effects, local atmospheric conditions, geographic location, and time of year.  The main objectives of this study are to estimate the long-term trend in LST using thermal remote sensing data. Accordingly, the average temperature in the region increased by about 0.5 ° C each year.
