| Outline of Final Research Achievements |
Japanese Greenhouse gas Observing SATellite (GOSAT) is the world’s first satellite dedicated to deriving greenhouse gas column-averaged dry air mole fractions from the troposphere to the top of atmosphere and more than nine years observation data have been released to the public. GOSAT cut a path through a wide range of researches such as GHG retrieval method from short wavelength IR spectra measured by satellite, validation method of satellite GHG data, surface flux estimation method by inverse calculation of atmospheric transport model. Much better precision in the GOSAT data is essential for achieving more outcomes, but it takes large effort to improve the retrieval method. In this study, advancement of methods for validation and empirical bias correction, which was feasible in a short time, was made.
