Abstract:
GOSAT-2 (Greenhouse gases Observing SATellite 2) was successfully launched in October 2018 and started its nominal operation in February 2019. GOSAT-2 project is a joint project by Ministry of the Environment, Japan Aerospace Exploration Agency (JAXA), and National Institute for Environmental Studies (NIES).

Currently, GOSAT-2 Level 1A products and FTS-2 (Fourier Transform Spectrometer 2) L1B products are being generated by JAXA, and CAI-2 (Cloud and Aerosol Imager 2) Level 1B and various Level 2 products are being generated by NIES. Both Level 1B products and selected Level 2 products are freely available from NIES’s GOSAT-2 Product Archive (https://prdct.gosat-2.nies.go.jp).

FTS-2 SWIR Level 2 products, derived by Full-physics method and Proxy method, are now being distributed to Research Announcement users for early evaluation. As of writing of this manuscript, FTS-2 SWIR Level 2 Proxy products from March to September 2019 have been generated. In these products, the global distributions and the temporal variations of methane (CH4), carbon monoxide (CO), and solar-induced chlorophyll fluorescence (SIF) are clearly seen.
In addition, the combined use of CH4 and CO data with carbon dioxide data from FTS-2 SWIR Level 2 Full-physics products will provide more information on the type of the emission sources.

Other GOSAT-2 products such as FTS-2 TIR Level 2 products and CAI-2 Level 2 aerosol products will be shown in the presentation. The status of GOSAT and GOSAT-GW will be also presented briefly.
