Abstract

Our main goal is to simulate the transport and spatial distribution of atmospheric pollutants in an urban environment in order to make air quality forecasts for the city of Budapest. For this task, we use the WRF-ARW meteorological model (The Weather Research & Forecasting Model - Advanced Research WRF, v3.6, 2014.) coupled with a chemistry transport model (WRF-Chem, v3.6, 2014.). The coupling between the meteorology and chemistry is online, which means that the model simulates the transport and chemical transformation of trace gases and aerosols simultaneously with the meteorology in each model time step (Grell et al., 2005). This allows the model system to take account of chemistry feedbacks on the meteorology (e.g., direct and indirect effects of aerosols). Our simulations run on a triple-nested domain with the 30 km horizontal resolution mother domain over Central Europe. The first nested domain with a horizontal resolution of 10 km over Hungary, and the finest resolution domain representing the area of the city of Budapest with 2 km grid spacing. The WRF-Chem model is capable of simulating the emission and transport of gases and aerosols from anthropogenic and biogenic sources depending on the choice of the chemical mechanism package. The steps of the model adaptation, a sensitivity analysis of the model, and some case studies are presented in this study.
