The Meteorological Synthesizing Centre West of the European Monitoring and Evaluation Programme (EMEP MSC -W, www.emep.int) has provided chemical transport modelling support to the UNECE Air Convention (unece.org/environmental-policy-1/air) since 1979. Over the years the modelling tools have developed from simple Lagrangian codes with horizontal resolution of ca. 150 km to 3-D Eulerian codes with scales ranging from ca. 1~km over limited areas to ca. 50 km for global scale calculations. The original focus on sulphur and acid deposition to ecosytems has developed into a strong focus on particulate matter (PM), and health metrics, with a massive increase in complexity. An offline extension of the EMEP model for urban areas (uEMEP) allows for estimates of some compounds to be made with resolutions of less than 100 m across Europe.

This talk will give a brief overview of the development of the EMEP models over the years, and illustrate some of the successes and issues associated with the current EMEP model, and with PM modelling in particular.
