CAMS Greenhouse Gas (GHG) flux inversions
Copernicus Atmosphere Monitoring Service produces global atmospheric inversion for methane, carbon dioxide and nitrous oxide using the atmospheric inversion framework PyVAR. The framework uses a process called data assimilation, or flux inversion, where ground-based and satellite remote-sensing observations are ingested into transport models of the atmosphere to infer the surface fluxes of greenhouse gases for the last few decades. For each species, there are different PyVAR versions depending on the period.
