The current status of GOSAT and GOSAT-2
Abstract
Greenhouse Gases Observing Satellite (GOSAT) and its successor, GOSAT-2, are Japanese earth observing satellites for greenhouse gases measurements from space. Both satellite projects are joint efforts among Ministry of the Environment (MOE), Japan Aerospace Exploration Agency (JAXA), and National Institute for Environmental Studies (NIES). GOSAT was launched in January 2009, already finished its design lifetime (five years), and is currently in its extended operation period. It has a Fourier transform spectrometer (FTS) for the measurements of columnar abundances of greenhouse and other gases and a UV-VIS-NIR-SWIR imager (CAI) for cloud and aerosol detection. 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. 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. Critical design reviews of GOSAT-2 spacecraft, earth observing instruments, and ground systems have been completed. Current status of GOSAT and GOSAT-2, including recent operation and achievements of GOSAT and developments of GOSAT-2 spacecraft, instruments, and ground data systems, will be presented.
