Here we document the CAMS reanalysis dataset, which currently covers the period 2003-2019June 2020, with additional years to be released in the future . The CAMS reanalysis is the latest global reanalysis data set of atmospheric composition (AC) produced by the Copernicus Atmosphere Monitoring Service, consisting of 3-dimensional time-consistent AC fields, including aerosols, chemical species and greenhouse gases, though GHG fields will only be released soon. The data set builds on the experience gained during the production of the earlier MACC reanalysis and CAMS interim reanalysis.
