PBM: Photochemical Box Model

DESCRIPTION

Its a simple numerical air quality model that simulates photochemical smog at an urban scale. It is best suited to treat low wind conditions, in presence of sun light. The urban area under study is subdivided into cells, whithin which chemical reactions are computed in particular to evalute the concentrations of hydrocarbons and ozone. It may deal with point, line and area sources. The pollutants considered are basically nitrogen oxydes and hydrocarbons.

Keywords

description: air quality, urban environment, light conditions
objectives: simulation, forecasting
application: short term, short range, ozone, hydrocarbons, point sources, line sources, area sources.
