EURO-DELTA - European Modelling Exercise

EURODELTA is initiated by the Task Force on Measurements and Monitoring (UNECE_TFMM) and the Task Force on Integrated Assessment Modelling (UNECE_TFIAM) and coordinated jointly by IIASA, EMEP, and JRC-IES. It includes the participation of 4 models (initially 6) (EMEP, REM (D), CHIMERE (F) and MATCH (S). To benefit from synergies between CityDelta and this activity, the comparison focuses on gas and aerosol phase coumpounds concentrations in 1999 for 8 different emission scenarios.

The purpose of the regional model inter-comparison is twofold:

-It will evaluate the performance of different regional models against an identified set of observations and quantify their performance in terms of agreed quality criteria.

-It will gain insight into the ability of regional atmospheric dispersion models to reproduce chemical nonlinearities in response to emission changes. The response to emission changes (the s/r relationships) is an important output from the chemical transport models used integrated assessment modelling for policy applications.

The model inter-comparison is carried out among models operating with long-term chemical transport simulations in regional scale (with a horizontal scale of ~50x50 km2). The results of this exercise will provide input to the review of the RAINS model, carried out in the frame of the CAFE programme.
