Offline coupling and verification of the unified emep model and worketa model

Abstract

In this paper the offline coupling of the Unified EMEP (European Monitoring and Evaluation Programme) model and WorkETA model was presented. For that purpose the meteorological driver was developed to supply the Unified EMEP model with input data from WorkETA model. To examine the use of the new driver, the Unified EMEP model was run from April to December 2005. The monthly and daily concentration of NO2, SO2 and SO42- obtained by using WorkETA driver was compared to measured values and to those obtained from the input data from parallel version of HIRLAM (High Resolution Limited Area Model), PARLAM-PS model. The analysis shows that the use of the new meteorological driver has more influence on the concentration of SO42- than on the concentration of NO2 and SO2.
