      abstract     = {The European MACC (Monitoring Atmospheric Composition and
                      Climate) project is preparing the operational Copernicus
                      Atmosphere Monitoring Service (CAMS), one of the services of
                      the European Copernicus Programme on Earth observation and
                      environmental services. MACC uses data assimilation to
                      combine in situ and remote sensing observations with global
                      and regional models of atmospheric reactive gases, aerosols,
                      and greenhouse gases, and is based on the Integrated
                      Forecasting System of the European Centre for Medium-Range
                      Weather Forecasts (ECMWF). The global component of the MACC
                      service has a dedicated validation activity to document the
                      quality of the atmospheric composition products. In this
                      paper we discuss the approach to validation that has been
                      developed over the past 3 years. Topics discussed are the
                      validation requirements, the operational aspects, the
                      measurement data sets used, the structure of the validation
                      reports, the models and assimilation systems validated, the
                      procedure to introduce new upgrades, and the scoring
                      methods. One specific target of the MACC system concerns
                      forecasting special events with high-pollution
                      concentrations. Such events receive extra attention in the
                      validation process. Finally, a summary is provided of the
                      results from the validation of the latest set of daily
                      global analysis and forecast products from the MACC system
                      reported in November 2014.},
