Comparison table

This table highlights major differences between the CAMS reanalysis, the MACC reanalysis and the CAMS interim reanalysis . There are many additional differences, in particular changes to the computation of individual atmospheric parameters (due to the change in the assimilation system from 36r1 and 40r2 to 41r2), differences due to changes in the assimilated atmospheric composition datasets that are not listed here.
