As the most prominent and complicated terrain on the globe, the Tibetan Plateau, with an elevation of more than 4000 m on average above mean sea leave (msl) makes up approximately one fourth of the land area of China. Long-term research on the Tibetan Plateau have shown that the giant prominence exerts thermal effects on the atmosphere, thus greatly influencing circulations over China, Asia and even the globe. Due to its topographic character, the plateau surface absorbs a large amount of solar radiation energy (much of which is redistributed by cryospheric processes), and undergoes dramatic seasonal changes of surface heat and water fluxes (Ye and Gao, 1979). The lack of quantitative understanding of interactions between the land surface and atmosphere makes it difficult to understand the complete energy and water cycles over the Tibetan Plateau and their effects on the Asian monsoon system with numerical models. Therefore, the study on land surface energy exchange and water cycle are regarded as the main task in the GEWEX (Global Energy and Water cycle Experiment) Asian Monsoon Experiment on the Tibetan Plateau (GAME/Tibet, 1996-2000) and CEOP (Coordinated Enhanced Observing Period) Asia-Australia Monsoon Project (CAMP) on the Tibetan Plateau (CAMP/Tibet, 2001-2005). The intensive observation period (IOP) and long-term observation of the GAME/Tibet and the CAMP/Tibet have been done successfully in the past 7 years. A large amount of data has been collected, which is the best data set so far for the study of energy and water cycle over the Tibetan Plateau. The purpose of this study is to analyze the characteristics of local and regional surface energy partitioning by using the field observational data and NOAA-14/AVHRR data collected during the GAME/Tibet and the CAMP/Tibet.
