| Name / Acronym: | GEMS |
| Full name: | Global and regional Earth-system (Atmosphere) Monitoring using Satellite and in-situ data |
| Description: | The GEMS project will create the first-ever system for operational global monitoring and medium & short range forecasts of atmospheric chemistry and dynamics. Much improved exploitation of the best available satellite and in-situ data will be achieved through assimilation into numerical models. By 2008, GEMS will produce near-real-time & retrospective analyses of greenhouse gases, reactive gases and aerosols in the troposphere and in the stratosphere on the regional and on the global scale. GEMS covers the atmospheric theme within GMES, and GEMS data products will provide valuable new analysis & forecast products for the GMES Service Element.
The global chemistry and aerosol forecast system will be developed and operated at The European Centre for Medium-Range Weather Forecasting (ECMWF). GEMS will develop estimates of the sources and sinks and of the inter-continental transport. The project will assess the impact of changes both on global and regional scale, examining extremes as well as means. Improved large-scale information from the ECMWF forecasts will improve regional forecasts that are used by air-quality authorities at city level across Europe. GEMS will deliver valuable new data products for the Global Monitoring for Environment and Security (GMES) Service Elements. In addition, key information relevant to the Kyoto and Montreal protocols and to the UN Convention on Long-Range Trans-boundary Air Pollution will be provided.
GEMS is European Integrated Project within the Sixth Framework Programme. It is co-funded by the European Commission (EC) and the Global Monitoring for Environment and Security (GMES) Atmosphere theme (EC&ESA). The GEMS consortium comprises 31 partners. This includes more than ten leading research labs with expertise on all aspects of atmospheric chemistry, the ECMWF with global operational weather capabilities, three environmental agencies, and ten regional centres, most with operational responsibilities for regional air-quality forecasting. The project is coordinated by Tony Hollingsworth (ECMWF). |
