The data product is provided in GeoTIFF format and include two temporal resolutions: 3 days and month. The 3-day data files include gridded XCO2 and mapping uncertainty, which are named like “MappingXCO2_Date.nc” and “MappingUncertainty_Date.nc”. The flag “Date” is defined as date ID of 1426 time-units started from 20 April 2009. The monthly data files only include XCO2 data and named like “MappingXCO2_YYYY_MM.tif”. The number of “YYYY” and “MM” represent year and month, respectively. The domain of the dataset covers global land ranging from 56° S to 65° N and 169° W to 180° E. The spatial reference of the dataset is Geographic Lat/Lon. The unit of XCO2 data is ppm while the nodata values were assigned to NaN.The National Key Research and Development Program of China2020YFA0607503The National Key Research and Development Program of China2016YFA0600303
