SHORTZ: Short Term Dispersion Model

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

area: air quality
objectives: simulation
description: gaussian plume, multiple point sources, multiple area sources, generic complex terrain, urban sites, rural environment, short term, inactive pollutant, deposition
