      abstract     = {The Global and Regional Earth System Monitoring Using
                      Satellite and In Situ Data (GEMS) project is combining the
                      manifold expertise in atmospheric composition research and
                      numerical weather prediction of 32 European institutes to
                      build a comprehensive monitoring and forecasting System for
                      greenhouse gases, reactive gases, aerosol, and regional air
                      quality. The project is funded by the European Commission as
                      part of the Global Monitoring of Environment and Security
                      (GMES) framework. GEMS has extended the data assimilation
                      system of the European Centre for Medium-Range Weather
                      Forecasts (ECMWF) to include various tracers for which
                      satellite observations exist. A chemical transport model has
                      been coupled to this system to account for the atmospheric
                      chemistry. The GEMS system provides lateral boundary
                      conditions for a set of 10 regional air quality forecast
                      models and global atmospheric fields for use in surface flux
                      inversions for the greenhouse gases. Observations from both
                      in situ and satellite sources are used as input, and the
                      output products will serve users such as policy makers,
                      environmental agencies, the science community, and providers
                      of end-user services for air quality and health. This
                      article provides an overview of GEMS and uses some recent
                      results to illustrate the current status of the project. It
                      is expected that GEMS will grow into a full operational
                      service for the atmospheric component of GMES in the next
                      decade. Part of this transition will be the merge with the
                      Protocol Monitoring for the GMES Service Element: Atmosphere
                      (PROMOTE) GMES project into the Monitoring of Atmospheric
