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.

Mardin ilinde uzun yıllar yer yüzey sıcaklığı değişiminin incelenmesi

Öz

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.
