Welcome

The EMEP models have been instrumental to the development of air quality policies in Europe since the late seventies, mainly through their support to the strategy work under the
Convention on Long-range Transboundary Air Pollution. In the 1990's the EMEP models became also the reference atmospheric dispersion model for use in the Integrated Assessment Models supporting the development of air quality polices under the EU Commission. While results from the EMEP models have been largely distributed to the international community through the EMEP programme, this is the first time that model code of one of the EMEP chemical transport models is publicly available.

This webpage releases the Unified EMEP model version rv3 together with a full input data set for 2005, under GPL license v3.

The Unified EMEP model is designed to calculate air concentrations and deposition fields for major acidifying and eutrophying pollutants, photo-oxidants and particulate matter. The present release of the model is intended to: Questions on the Unified EMEP model can be addressed to emep.mscw@met.no. Support to the user community will be developed here with your contribution.
