Global land 1° mapping XCO2 dataset using satellite observations of GOSAT and OCO-2 from 2009 to 2020

The global 1° land mapping XCO2 dataset (Mapping-XCO2) is derived from satellite XCO2 retrievals of GOSAT and OCO-2 spanning the period of April 2009 to December 2020. 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.
