Influence of WRF parameterization on air quality modeling

Within the research with the NWP WRF model, various tests were made with implementation of the new, improved mixing length in MYJ PBL scheme. Default and modified setup of the NWP WRF model were both later coupled with dispersion models. This study presents the continuation and exploration of the research by application of regional and high resolution air quality models. On larger scale regional EMEP model was used to simulate long range and trans-boundary transport of various pollutants during the episode of high PM10 values when observed daily values reached ~ 140 µg/m3 at stations in continental part of southeastern Europe. Furthermore CAMx high resolution model was applied to evaluate the contribution of local anthropogenic sources. Experiments with AQ models encompassed different time periods. Using complex atmospheric chemistry models it was possible to analyze the main processes contributing to the relatively high concentration on regional and local scale and to compare the performance of two different air quality models.
