[ACG49-03] GOSAT collaboration activities with OCO-2 for calibration and validation
Keywords:CO2, GOSAT, Calibration, Validation, OCO-2
JAXA has been operating a ground-based FTS with high spectral resolution at Saga University as a member of the Total Carbon Column Observing Network (TCCON) since July 2011. XCO2 and XCH4 are estimated from direct sunlight spectra with high accuracy. TCCON dataset is utilized to make validation for the satellite observations such as GOSAT and OCO-2 with simultaneous measurements. GOSAT team also conducts the calibration and validation campaign at Railroad Valley, Nevada US desert every summer season collaborated with OCO-2 team. We also measure XCO2 and XCH4 by a portable FTS on the field. We will present our activities.
