[ACG46-31] Eight Years of GOSAT Operation in Space and New Science from GOSAT-2
GOSAT was launched in January 2009 and has been operated for more than eight years. It has a Fourier transform spectrometer (FTS) for the measurements of columnar abundances of carbon dioxide (CO2) and methane and a UV-VIS-NIR-SWIR imager (CAI) for cloud and aerosol detection. Its data are being used in various scientific researches related to climate change and atmospheric pollution monitoring such as monitoring of whole-atmosphere monthly mean carbon dioxide concentration, evaluation of inventories for anthropogenic emissions of CO2 and methane, and PM2.5 mapping in asian urban regions.
GOSAT-2 will be launched in FY2018. GOSAT-2 instruments (FTS-2 and CAI-2) will be modified or improved based on the experiences of GOSAT instruments. FTS-2 will have the extended spectral coverage for carbon monoxide measurement and the intelligent pointing capability to avoid cloud contamination. CAI-2 will have multiple UV bands for more precise land aerosol monitoring and the forward/backward viewing capability to avoid sun glint over oceans. GOSAT-2's spacecraft, instruments, and ground data processing systems are currently being manufactured.
In this presentation, several scientific achievements based on GOSAT's eight-year GHG data and new science expected from GOSAT-2 will highlighted.
