INTERNET Operational Air Quality Modelling: Bilbao (Spain) and Leicester (UK)

In this contribution we show the performance of two applications running over the Internet into the EQUAL EU DGXIII project (Equal Services for a better Quality of Life) corresponding to the Bilbao (Spain) and Leicester (UK) city domains. The OP ANA model was running for these city domains in the UPM laboratories (Environmental Software and modelling Group) since May, 1, 2000 to July, 31, 2000 for a testing period into the EQUAL project. Wee have used the OPANA modelling system which composed by composed by a complex non-hydrostatic meteorological module (REMEST) based on the MEMO model (University of Karlsruhe, 1994) and a chemical module (CHEMA) based on the SMVGEAR implicit method developed in Los Angeles University (1994). Both modules are copied on-line and the advection and diffusion of the primary emissions are driven by the meteorological module. Five different data sets are used to run the OPANA air quality modelling system: 1) Topography, 2) Landuse files 3) emission data 4) initial meteorological data and 5) air quality monitoring data (from the city network). A web interface has been created to allow the Internet user to mine the air pollution forecasted data on the Web and creating on-line the information which is interest for the user (citizen or air quality authorities. The Internet based operational application provides a unique additional value for the user on the Web which can be used for future emission strategic plans from the air quality authorites. On the other hand, the system was operating wih a very high sucess considering the daily access of meteorological and air pollution data in the web by using automatic scripts and JAVA applications.
