AN ENVIRONMENT SIMULATION AND MONITORING-SYSTEM FOR URBAN AREAS

A prototype of an environmental simulation and monitoring system for u rban areas has been developed. This system provides state-of-the-art a ir and water pollution calculation and analysis tools. A distributed c lient-sewer architecture based on the Internet has been chosen to allo w authorities to run large models requiring HPC hardware on remote mod el sewers. The main focus of this paper is the description of a model designed for the computation of the extra ozone production in urban ar eas and for short-term ozone forecast purposes. Within the framework o f an integrated simulation and monitoring system, this model benefits from the easy exchange of modeled and monitored data. Automatic interf aces to monitoring nets allow an operational use of the model.
