Global CO2 Distribution

The Global CO2 Distribution product provides information on global CO2 mole fractions based on the results of numerical simulation using observation data from various sites worldwide. It demonstrates temporal and spatial variations in CO2 mole fractions from various perspectives.
Column-average CO2 mole fraction (XCO2)* data were added on 7 March 2024. Grid point data (NetCDF format) can be downloaded from this Global CO2 Distribution page.
