Operational street pollution model (OSPM) for simulating the dispersion of ............ .
The Operational Street Pollution Model (OSPM) is an atmoshpheric dispersion model for simulating the dispersion of air pollutants in so-called street canyons. In OSPM concentrations of traffic-emitted pollution is calculated using a combination of a plume model for the direct contribution and a box model for the recirculating part of the pollutants in the street.
