The model MARS/MUSE was developed in the LHTEE, in order to simulate the dispersion and the chemical transformation of reactive species in the local-to-regional scale.
Processes of emission, dispersion, transformation and deposition of pollutants are calculated on a staggered grid in terrain-influenced co-ordinates, while chemical transformations can be treated using any suitable chemical reaction mechanism.
In order to apply model MARS/MUSE, the following input data are required:
a) meteorological input derived from the application of prognostic wind field model MEMO,
b) orography and land use data for the area of interest,
c) emission data of photochemical pollutant, and
d) Initial and lateral boundary concentrations for the main photochemical pollutant.
The model has been applied successfully for the estimation of air quality in various urban areas in Europe.
