The lectures and discussions at the workshop focussed especially on the importance of the linkage between the modelling processes and the measuring tools.
Measurements play two significant roles in air pollution modelling.
At first, the usage of measured meteorological, emission and background concentration data as input for air quality simulations obviously influences the quality of the simulation results, especially for air quality forecasts. At second, measurement data are one of the basic preconditions for the validation of air quality models. The proposed date of the 4th workshop is the time between mid October and mid November this year. The program was wound up by a tour of the Computer Science School at UPM, and by a common dinner in a typical Madrid restaurant.
