Co-operative Programme for Monitoring and Evaluation of the Long-Range Transmission of Air pollutants in Europe[1]


EMEP was founded by UN ECE, WMO, and UNEP in 1977. In 1983 it became a project under the Convention on Long-Range Transboundary Air Pollution. The main objective of the EMEP Programme is to regularly provide Governments and subsidiary bodies under the Convention on Long-Range Transboundary Air Pollution with qualified scientific information to support the development and further evaluation of the international protocols on emission reductions negotiated within the Convention. The EMEP programme relies on three main elements: (1) collection of emission data (EMEP collects precipitation chemistry data from 106 ground level monitoring stations in 25 European countries), (2) measurement of air and precipitation quality and (3) modelling of atmospheric transport and deposition of air pollution.[1]

In 1999 it was decided to include integrated assessment into the core activities of EMEP and to establish a Centre for Integrated Assessment (CIAM) at the International Institute for Applied Systems Analysis. Building on past modelling work, in particular the RAINS model, the CIAM provides the UN ECE Task Force on Integrated Assessment with:

  • Abatement options for reducing emissions of SO2, NOx, VOC, NH3 and particulate matter, including structural measures in the energy, transport and agricultural sector, and their costs
  • Projections of emissions
  • Assessment of the atmospheric transport of substances
  • Analyses of the environmental and health effects and the economic benefits of emission reduction.

In addition to integrated assessment models, EMEP uses Chemical Transport Models developed at the Meteorological Synthesizing Centre - East (MSC-E) and at the Meteorological Synthesizing Centre - West (MSC-W). MSC-E models are MSCE-E/HM and MSC-E/POP which are concerned with the regional atmospheric dispersion and deposition of heavy metals and selected persistent organic compounds. MSC-W models are concerned with the regional atmospheric dispersion and deposition of acidifying and eutrophying compounds, ground-level ozone and particulate matter. The MSC-W models are the Unified EMEP Model, the EMEP Lagrangian Acid Deposition Model, and the EMEP Lagrangian Photooxidant Model.[1]

Models used within the Project/Programme:

  • Unified EMEP Model
  • EMEP Lagrangian Acid Deposition Model
  • EMEP Lagrangian Photooxidant Model
