For understanding the interaction between vegetation and atmosphere over paddy field, a rain-fed paddy field, micrometeorological observation site, Sukhothai has been started since March 1997. This observation site, located in the Chaophraya river basin, is one of the sites in the framework of the GAME project. From the eight-year data analysis, it was found that the submerge process was different between 1999 and 2005. This indicates that water resource management is changing from purely rain-fed to carry water to farms such as artificial flood. From surface energy fluxes observations, it was found that the timing of decreasing submerge water is important for estimation of water budget on rain-fed paddy field. In the dry season, it was found that dew condensation is strongly related to evaporation with low surface temperature in the early morning and non-low amount of water vapor even in the dry season.
