 For validating the Level 2 column abundances of CO2, the team uses data from ground-based high-resolution Fourier transform spectrometers (TCCON: Total Carbon Column Observing Network) and in-situ observation instruments installed on aircrafts.
The bias-corrected FTS SWIR (Short-Wavelength InfraRed) Level 2 CO2 products (V02.75) are the results of the bias-corrections which are conducted on the column-averaged dry air mole fractions of carbon dioxide (XCO2) of the FTS SWIR Level 2 CO2 products (V02.72) using the ground-based observation data of the TCCON.

 Among all spectra obtained with FTS, only those measured under no cloud interference within IFOV are selected for further processing. This screening uses the images from Cloud and Aerosol Imager (CAI). Based on the absorption characteristics of the gases, the selected spectra are analyzed, using a numerical calculation scheme called the retrieval method, to calculate column abundances of CO2.

 [Monthly] The monthly data (bias-corrected FTS SWIR Level 3 CO2 products V02.75) are not provided on this website. The data are only used to draw the images on the Gallery page. If you need the data file of the monthly data, please visit "GOSAT Data Archive Service (GDAS)" https://data2.gosat.nies.go.jp/.
The FTS SWIR Level 3 CO2 products store the monthly global distributions of CO2 that are calculated from the FTS SWIR Level 2 column abundances of CO2. A geostatistical calculation technique called Kriging method is applied to estimate values for blank regions in the FTS SWIR Level 2 distributions. Values gridded into 2.5-degree cells are provided.
