Based on satellite and in-situ observations, the CAMS service produces daily analysis, forecasts as well as reanalyses. As one of the service products, CAMS is producing global-scale reanalyses, one for the greenhouse gases, and one for the reactive gases and aerosol concentrations. The production of these reanalyses has started early 2017. The reactive gases and aerosols reanalysis for the period 2003-2016 became available in October 2018 (Inness et al., 2019). For the greenhouse gases, the validation report for the period 2003-2005 became available in July 2018 (Ramonet et al., 2018). The CAMS reanalysis will be further extended in the years up to 2021, catching up with real-time. This document presents the validation results for the greenhouse gases (CO2, CH4) for the first 8 years of the reanalysis run, period 2003 - 2010.
