N1  - GEMS is funded by the European Commission under the EU Sixth Research Framework Programme, Contract SIP4-CT-2004-516099. We are very grateful to our project officer Dr. Peter Breger for his consistent help and enthusiasm in developing and launching the GEMS program. We also acknowledge the many agencies that provided observational data. Guido van der Werf (Vrije Universiteit Amsterdam) has kindly resampled the GFEDv2 inventory to 8-day time resolution. Louis Gonzalez (LOA USTL) kindly provided the MODIS image (online at http://loaamma.univ-lillel.fr/ modissurvey; http://loaamma.univ-lillel.fr/AMMA). Dr. Anthony Hollingsworth sadly passed away on 29 June 2007. He was the initiator and coordinator of the GEMS project and is greatly missed as a person and for his significant contributions to the atmospheric sciences.
AB  - 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 Composition and Climate (MACC) project.
