Abstract
Three dimensional air quality modelling systems have experienced a
considerable advance during the last decade. Sophisticated numerical methods
have also been developed to gather most of the computer capabilities, which
have also experienced important advances. Parallel computing is also an option
that is considered more and more important nowadays due to the relatively slow
process of single computer processors during recent years. In this contribution
we have implemented an air quality real-time operational forecasting system that
covers all of Europe by using the MM5-CMAQ-EMIMO air quality modelling
system. This system is a step forward from the already developed system that
covered the Iberian Peninsula in 2002. The CMAQ 4.5 version (September,
2005) has been incorporated into the application. MM5 and CMAQ models are
respectively the meteorological mesoscale and the dispersion drivers. The
EMIMO model has been progressively updated by using the new Corine Land
Cover for Europe (EEA) with 100 m spatial resolution. We have developed a
GIS oriented Internet interface that allows the user immediate access to pollution
time series and hourly maps for the next 48-72 hours forecast for criteria
pollutants (those limited by the corresponding EU Directives). The visual
information is adapted to the specific legislation for each pollutant so that the
information is related to the possible exceedances of the different concentrations
averaged over different periods of time.
