I’d like to use the Copernicus anthropogenic CO2 data to spatially derive the kilogram quantities emitted for a given year. I’m currently looking at using the CAMS-GLOB-ANT_v4.2_co2_2018.nc_sum data set. However, the units I’m assuming are in column density per month, giving kgm-2s-1, in which case I would need your help/advice on how to perform the conversion to kilograms.
