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).
