Abstract
Validation plan for GOSAT-TANSO products is described in this article. The validation will be started 3 months after launch. The present main ideas of acquiring validation data for TANSO-FTS SWIR L2 products of the column abundance of CO2 and CH4 are as follows. A ground-based high-resolution Fourier transform spectrometer will be installed and co-located with a lidar and a sky-radiometer at some stations for extensive validation data acquisition. In-situ measurements and/or sampling of CO2 and CH4 onboard commercial and charter aircrafts will be also employed. National Institute for Environmental Studies (NIES) GOSAT project team and as well as other organizations responsibly concerning with GOSAT project, research teams selected through Research Announcement (RA) will conduct the validation of products.
