Evaluation of AirGIS: a GIS–based air pollution and human exposure modelling system
This study describes in brief the latest extensions of the Danish Geographic Information System (GIS)–based air pollution and human exposure modelling system (AirGIS), which has been developed in Denmark since 2001 and gives results of an evaluation with measured air pollution data. The system shows, in general, a good performance for both long–term averages (annual and monthly averages), short–term averages (hourly and daily) as well as when reproducing spatial variation in air pollution concentrations. Some shortcomings and future perspectives of the system are discussed too.
