WebObserved concentrations, using both in situ and satellite observations, are compared with model-simulated concentrations, and the surface fluxes in the model are gradually adjusted until the differences are close to zero. This process is called atmospheric inversion, and is used by CAMS to update global estimates of net fluxes annually.
