AB: Under the umbrella of European Global Monitoring for Environment and Security (GMES) the Global and regional Earth-system (Atmosphere) Monitoring using Satellite and in-situ data (GEMS) project has been running since March 2005. The aim of the project is to build a pre-operational system that will assimilate both satellite and in- situ observations to monitor atmospheric composition. Greenhouse gases, reactive gases, and aerosol are all monitored in a global 4-dimensional variational (4D-Var) data assimilation system running at about 1 degree resolution. These global fields are then used as boundary conditions for regional air quality modelling on the European scale. Both the global and regional component will improve our understanding of surface fluxes, long- range transport, and in general the causes of poor air quality. We will present an overview of the project and show how we combine state-of-the-art modelling, data assimilation and retrieval techniques to support scientific research, air quality forecasters, and environmental policy makers.
