Abstract

Development and Evaluation of the Urban Dispersion Model EPISODE A contribution to subproject SATURN SE Walker, L.H. S10rdal, C. Guerreiro, K.E. Gr0nskei and S. Solberg Norwegian Institute for Air Research, P.O. Box 100, N-2007 Kjeller, Norway As a basis for modern air quality management work in urban areas, there is a need for urban scale dispersion models capable of estimating time-varying (hourly) concentrations at arbitrary receptor points within the urban area. Such models should be able to specify the time-varying pollutant gradients even close to sources. The air pollution dispersion model EPISODE has been developed at NILU over several years in order to meet these needs (Walker, 1997). In Oslo, the model currently forms part of NILU's Air Quality and Information System (AirQUIS), a modern PC-based system for air quality surveillance and management work. Earlier versions of the model have been
