Abstract

Continuous validation of data observed by satellites, such as Greenhouse gases Observing SATellite (GOSAT), is important to qualify the long-term trends of greenhouse gases. High-precision data over the restricted region measured by ground-based high-resolution Fourier transform spectrometers (g-b FTS), airborne in-situ instruments, and flask sampling devices have been used for the validation of satellite data. As part of CAL/VAL (Calibration/Validation) activities of the GOSAT, airborne flight campaigns were performed over Tsukuba and Moshiri using the ground-based FTS, airborne in-situ and flask devices, and 1.57-μm Laser Absorption Sensor (LAS). Airborne flask sampling and insitu carbon dioxide (CO2) sensors were carried out to obtain vertical profiles of the CO2 mixing ratio while ground-based FTS and LAS measured solar direct spectra and weighted column-averaged CO2, respectively. Those results were used to decide a calibration factor of the ground-based FTS and compared with GOSAT products over Tsukuba. We will report the comparison results of the aircraft campaign measurements and the retrieval value from the FTS.
