Calculation land surface temperature depening on becker and Li-1990 algorithm [Yer yüzey sicaicliginin becker ve Li-1990 algori·tmasina bagli hesaplanmasi]

Land surface temperature is an important factor for determination of most physical, biological, energy and water processes and cycles, weather prediction, global ocean circulation and climatic variability in the earth. Further, knowledge of land surface temperature is necessary for management of earth energy resources and environmental studies. For these aims, land surface temperature maps were constituted by using NOAA-12, 14, 15/AVHRR satellite data. Cities of Adana, Ankara, and Antalya, Artvin, İstanbul, İzmir, Kayseri, Konya, Malatya, Samsun, Sivas, Şanhurfa and Van were chosen as control points on the maps. The values which were obtained from the maps produced were compared with these ground-truth values. On monthly avereges of overall comparisons, the correlation coefficient (r) and root mean squared error (RMSE) value Were found to be 0, 989 and 1, 493 °K respectively. When the separate cities were considered, correlation coefficient and RMSE values were found to change within the intervals 0, 959-0, 990 and 1, 589-3, 332 °K respectively. These show that land surface temperatures can be determined with a high accuracy by using the data from NOAA-AVHRR satellites. ©2010 TIBTD Printed in Turkey
