GOSAT-2/L2/SWIR CO2 column-averaged dry-air mole fraction(G2-01)
- Environmental
L2 CO2 column-averaged dry-air mole fraction data retrieved from SWIR radiance spectral data observed by TANSO-FTS-2 onboard GOSAT-2, which was developed as a joint project by the Ministry of the Environment (MOE), the National Institute for Environmental Studies (NIES), and the Japan Aerospace Exploration Agency (JAXA).

| Notes | The L2 column-averaged dry-air mole fraction (SWIR) is a product that stores column-averaged dry-air mole fraction of atmospheric gases retrieved by the MAP method (full-physics method) using Band 1-3 radiance spectral data of TANSO-FTS-2 (generated for cases where cloud-free or only optically thin cirrus clouds are present within the TANSO-FTS-2 instantaneous field of view). On Tellus, point cloud data in 'HDF5' format, which is published by the GOSAT-2 Product Archive, is converted into 'FlatGeobuf' and 'GeoJSON' formats. |
