MACC, which stands for Monitoring Atmospheric Composition and Climate, started on 1^st June 2009 and will run for 29 months. The project has an estimated total cost in excess of EUR 16 Millions and is partly funded by the European Commission under the 7^th Framework Programme. MACC builds on the work of the FP6 projects GEMS and the ESA-funded GMES Service Element project PROMOTE.

MACC monitors the global distributions and long-range transport of greenhouse gases such has carbon dioxide and methane, aerosols that result from both natural processes and human activities, and reactive gases such as tropospheric ozone and nitrogen dioxide. It evaluates how these constituents influence climate and estimates their sources and sinks.

MACC also provides specific products covering Europe:

• Maps and data for regional air-quality forecasts;
• Retrospective assessments of air quality;
• Identifications of sources of pollution episodes;
• Toolbox for evaluating possible emergency emission control measures;
• Inputs to local air-quality forecasts, health information and warnings.

Access atmospheric environmental services.

MACC is undertaken by a consortium led by the European Centre for Medium-Range Weather Forecasts (ECMWF) and composed of 45 partners. For more information and access to the services, please visit www.gmes-atmosphere.eu
