Numerical Study of Regional Air Pollution Transport and Photochemistry in Greece

Ioannis C. Ziomas; Paraskevi Tzoumaka; D. Balis; Dimitrios Melas; Dionisis Asimakopoulos; Georgia Sanida; Panagiotis Simeonidis; I. Kioutsioukis; C. Zerefos

The aim of the present project is to study the transport and photochemistry of regional air pollution in Greece using numerical models, a higher-order turbulence closure dynamic model coupled with an Eulerian photochemical dispersion model. The model used for the simulation of the three-dimensional wind field and the boundary layer structure is developed at the Department of Meteorology, Uppsala University (MIUU) while the calculations of pollutant concentrations were performed using the Urban Airshed Model (UAM).

The Urban Airshed Model (UAM) is a three dimensional grid (Eulerian) model which calculates the concentrations of both inert and chemically reactive pollutants by simulating the physical and chemical processes in the atmosphere that affect pollutant concentrations. The UAM simulates the emission, advection and dispersion of pollutants within every grid cell of the modelling domain.
