GOSAT (Greenhouse gases Observing SATellite) and GOSAT-2 are a Japanese Earth observation satellites for greenhouse gas measurements from space and launched in 2009 and 2018, respectively. These satellits were developed and have being operated by Ministry of the Environment, JAXA (Japan Aerospace Exploration Agency), and NIES (National Institute for Environmental Studies).

NIES is responsible for the generation of GOSAT and GOSAT-2 Level 2 and Level 4 standard products such as:

1) L2 cloud flag
2) L2 CO2 column amount (SWIR)
3) L2 CH4 column amount (SWIR)
4) L2 H2O column amount (SWIR)
5) L2 CO2 profile (TIR)
6) L2 CH4 profile (TIR)
7) L4A global CO2 flux
8) L4A global CH4 flux
9) L4B global CO2 distribution
10) L4B global CH4 distribution

1) GOSAT-2 TANSO-CAI-2 L2 Cloud Discrimination Product
2) GOSAT-2 TANSO-CAI-2 L2 Aerosol Property Product
3) GOSAT-2 TANSO-FTS-2 SWIR L2 Chlorophyll Fluorescence and Proxy-method Product
4) GOSAT-2 TANSO-FTS-2 SWIR L2 Column-averaged Dry-air Mole Fraction Product
5) GOSAT-2 TANSO-FTS-2 TIR L2 Cloud and Aerosol Property Product
6) GOSAT-2 TANSO-FTS-2 TIR L2 Temperature and Gas Profile Product
7) GOSAT-2 L4A Global CO2 Flux Product
8) GOSAT-2 L4A Global CH4 Flux Product
9) GOSAT-2 L4B Global CO2 Distribution Product
10) GOSAT-2 L4B Global CH4 Distribution Product

All the GOSAT Level 2 and 4 standard products are freely available to the public. As for GOSAT-2, GOSAT-2 TANSO-FTS-2 SWIR L2 Column-averaged Dry-air Mole Fraction Product is being distributed to PIs of GOSAT Series Research Announcement.

In this presentation, the latest status and the future plans of these higher-level products will be introduced.
