GEOS-CHEM global 3-D chemical transport model (CTM) - CH4, C2H6, CO, Acetone, O3

GEOS-Chem is a global 3-D chemical transport model (CTM) for atmospheric composition driven by meteorological input from the Goddard Earth Observing System (GEOS) of the NASA Global Modeling and Assimilation Office. This dataset contains gridded global monthly averages of methane, ethane, carbon monoxide, acetone, and ozone.
