Estimation of land surface temperature retrieved from EOS/MODIS in Naqu area over Tibetan Plateau
青藏高原那曲地区MODIS 地表温度估算

Using split window algorithms developed by Sobrino, added a suff icient and simple cloud detection process for MODIS L1B data. Then based on land surface classif ication (land, water, snow & ice), retrieved four land surface temperature images for clear sky in Naqu area over Tibetan Plateau in January, April, June and October in 2007, respectively. After that the derived LST was compared with the MODIS daily land surface temperature product and in-situ data from the Coordinated Enhanced Observing Period (CEOP) Asia-Australia Monsoon Project (CAMP) on Tibetan Plateau (CAMP/Tibet). The results showed that the LST derived from the improved Sobrino method was in good accordance with the MODIS product and the average difference between LST and in-situ measurements was only 1.435 K.
