This paper collected time series of MODIS land surface temperature (LST) data, together with meteorological data of 137 stations and ASTER GDEM data for 2001-2007, to estimate and map the spatial distribution of monthly mean air temperatures in the Tibetan Plateau and its neighboring areas. Time series analysis and both ordinary linear regression (OLS) and geographical weighted regression (GWR) of monthly mean air temperature (Ta) with monthly mean land surface temperature (Ts) were conducted. GWR analysis with independent variables of MODIS Ts and altitude provide good estimation of Ta. According to the GWR estimated temperatures of the Tibetan Plateau, more spatio-temporal details of the plateau temperature are acquired. The mean temperature in July (the warmest month) at altitudes of 4500 m can reach 10°C. This may help explain why the highest timberline in the Northern Hemisphere is on the Tibetan Plateau
