Abstract :
Methane is one of the main souse of global warming and its emission from rice paddy field is a big issue. To fully investigate the special and temporal distribution of methane emission from rice paddy, we utilize the rice crop calendar mapping and ground water coverage data from satellite observation for IPCC 2006 guidelines. Then, global methane emission inventory from rice paddy is estimated. Comparison between atmospheric methane concentration from GOSAT and estimated methane emission inventory in regional scale is done and positive relationship between them is found.
