- Abstract:
-
Land surface temperature (LST) is very important in surface energy balance,which plays a key role in the interactions between ground and atmosphere.Studying the dynamic mutative disciplinarian of LST in Hu’nan province based on MODIS data can provide fundamental data for affection of urban heat island,and monitoring and protecting of natural resources.Besides they can be scientific foundation for decision making,based on introducing and analyzing the algorithms commonly used to retrieve surface temperature,a Split-Window Algorithm is chosen to retrieve the surface temperature due to the data on hand and the results of LST is validated with the highest air temperature obtained from meteorological stations.The results show that the caloric increases from northwest to southeast which is divided into two parts by Wuling mountain and the eastern piedmont of Xuefeng mountain.The retrieved LST and the highest actual temperature have the similar trend and the result is more rational.
