Monthly Maps of Global XCO Distribution Derived from
GOSAT-2 FTS-2 SWIR L2 Products (Spatial interpolation and extrapolation are applied)

These maps are derived from GOSAT-2 FTS-2 SWIR L2 product (GOSAT-2 TANSO-FTS-2 SWIR L2 Column-averaged Dry-air Mole Fraction Product V02.00) with spatial interpolation and extrapolation using the algorithm similar to that used for GOSAT FTS SWIR L3 product generation*.
