SHORTZ: Short Term Dispersion Model

DESCRIPTION

The air quality model SHORTZ uses a simple gaussian plume formulation to evaluate ground level concentrations due to up to 300 point and area sources in urban and rural areas with flat or complex terrain conditions. It may include sedimentation and works on short time intervals (1,2, 3 hours).

Keywords

description: air quality, gaussian plume, multiple point sources, multiple area sources, complex terrain
objectives: simulation
application: urban environment, rural environment, short term, area sources, point sources, complex terrain, non reactive pollutant, deposition
