چکیده
As discussed in Sect. 3.2, it was difficult to compare GOSAT XCO2 with aircraft measurement data at some observation sites where there was a paucity of flight data on the day when GOSAT was scheduled to overpass. However, the temporal interpolation of aircraft-based XCO2 by a curve fitting method enables temporally matched cases to be obtained for all observation sites of CONTRAIL, NOAA, DOE, and NIES (41 sites). Based on Miyamoto et al. (2013), we attempted to fit aircraft-based XCO2 with the following equation (S.1) containing annual trend and annual / semiannual sinusoidal variations.

Validation of XCO2 derived from SWIR spectra of GOSAT TANSO-FTS with aircraft measurement data
Column-averaged dry air mole fractions of carbon dioxide (XCO2) retrieved from Greenhouse gases Observing SATellite (GOSAT) Short-Wavelength InfraRed (SWIR) observations were validated with aircraft measurements by the Comprehensive Observation Network for TRace gases by AIrLiner (CONTRAIL) project, the National Oceanic and Atmospheric Administration (NOAA), the US Department of Energy (DOE), t...
متن کاملValidation of XCH4 derived from SWIR spectra of GOSAT TANSO-FTS with aircraft measurement data
Column-averaged dry-air mole fractions of methane (XCH4), retrieved from Greenhouse gases Observing SATellite (GOSAT) short-wavelength infrared (SWIR) spectra, were validated by using aircraft measurement data from the National Oceanic and Atmospheric Administration (NOAA), the US Department of Energy (DOE), the National Institute for Environmental Studies (NIES), the HIAPER Pole-to-Pole Observ...
متن کاملComparison of Retrieved L2 Products from Four Successive Versions of L1B Spectra in the Thermal Infrared Band of TANSO-FTS over the Arctic Ocean
This paper concentrates on the calibration/validation of the Thermal and Near Infrared Sensor for Carbon Observation (TANSO)–Fourier Transform Spectrometer (FTS) spectra in the thermal infrared (TIR) spectral region (B4 band) over the Arctic Ocean. We have performed inter-comparisons of the retrieved L2 products from four successive versions of L1B products (V150, V160, V201, V203) to check the...
متن کاملPreliminary validation of column-averaged volume mixing ratios of carbon dioxide and methane retrieved from GOSAT short-wavelength infrared spectra
Column-averaged volume mixing ratios of carbon dioxide and methane retrieved from the Greenhouse gases Observing SATellite (GOSAT) Short-Wavelength InfraRed observation (GOSAT SWIR XCO2 and XCH4 ) were compared with the reference calibrated data obtained by ground-based high-resolution Fourier Transform Spectrometers (g-b FTSs) participating in the Total Carbon Column Observing Network (TCCON)....
