Tropospheric Aerosol Modelling

The emphasis in 2002 has been on the further development of aerosol modelling within the 3-D Eulerian chemistry-transport model LOTOS. The aim is to extend the model with all aerosol compounds contributing to the Aerosol Optical Depth (AOD), so that comparison with and (later) data assimilation of retrieved AOD fields from satellites is possible. Within the year 2002 no data assimilation of AOD fields from satellites has been performed, mainly due to a lack of funding. However, the model was extended substantially and extensive validation has taken place.
