GOSAT/L2/TIR CH4 vertical profile(Day side)(G1-05-1)
- Environmental
L2 vertical profile of CH4 concentration (Day side) data retrieved from TIR radiance spectral data observed by TANSO-FTS onboard GOSAT, 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 CH4 vertical profile (TIR) is a product that stores vertical profile of CH4 concentration retrieved by the MAP method using Band 4 radiance spectral data of TANSO-FTS (generated for cases cloud-free condition within the TANSO-FTS instantaneous field of view). On Tellus, point cloud data in 'HDF5' format, which is published by the GOSAT Data Archive Service, is converted into 'FlatGeobuf' and 'GeoJSON' formats. The original data, when expanded, is structured as one file per day. However, here it is organized as one file containing one month's worth of observations. Additionally, the file structure is separated into insolation day and night observation data. |
