[ACG10-23] The current status of GOSAT and GOSAT-2
GOSAT was launched in January 2009, already finished its design lifetime (five years), and is currently in its extended operation period. Its data have been used to calculate whole-atmosphere monthly mean carbon dioxide concentration and to identify locations with large anthoropogenic emissions of CO2 and methane.
GOSAT-2 will be launched in FY2017. Both satellites have Fourier transform spectrometers for the measurements of columnar abundances of greenhouse and other gases and UV-VIS-NIR-SWIR imagers for cloud and aerosol detection. GOSAT-2 instruments (FTS-2 and CAI-2) will be modified or improved based on the experiences of GOSAT instruments (FTS and CAI). 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 forward/backward viewing capability to avoid sun glint over oceans. Most of critical design reviews of GOSAT-2 spacecraft, earth observing instruments, and ground systems have been completed.
