Abstract :
In this study, we determined the concentration of global methane (CH4) emission using SCIAMACHY data. We analyzed land and sea area to investigate the nine-year changes of CH4 concentration from 2003 to 2011. Where we subtracted the CH4 concentration in land and sea during 9 years. As a result, we found that the growth rate of global CH4 concentration is 3-5ppb/year in land. It was cleared that a big amount of CH4 emission concentration was found not only in paddy fields in the Northern Hemisphere but also in broadleaf evergreen areas in the Southern Hemisphere (Central Africa and South America).
