Relationship between the geographical features of methane sources of SCIAMACHY and vegetation index of MODIS

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. 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). We compared with the precipitation and EVI to Broadleaf Evergreen Forest and paddy field which emitted a lot of CH₄. As a result, we understood that paddy field in Southeast Asia has a strong correlation with EVI and Broadleaf Evergreen Forest has a strong correlation with precipitation.
