Summary: The WRF-Chem model has been applied to study two specific episodes of pollution from the Nikel and Zapolyarny facilities, the summer episode 2007 and winter 2010/11. Meteorological input data from WRF compare well with data from ECMWF. The model underestimates concentrations of SO2 in specific episodes, a possible explanation for this is that the flue gas plume is levelled out in the model, in addition little is known about the emissions. A budget for the different processes show that chemical loss and wet deposition are most important in summer time, while wet and dry deposition are most important in winter time. WRF-Chem is computational demanding and most suited to study processes and specific episodes.
