  Screen Model

Version 11.0 - October 2016

Description
This program is based on the well-known EPA Screen3 model. The SCREEN3 model was developed to provide an easy-to-use method of obtaining pollutant concentration estimates based on the screening procedures document. The program can perform all of the single source, short-term calculations in the screening procedures document, including estimating maximum ground-level concentrations and the distance to the maximum, incorporating the effects of building downwash on the maximum concentrations for both the near wake and far wake regions, estimating concentrations in the cavity recirculation zone, estimating concentrations due to inversion break-up and shoreline fumigation and determining plume rise for flare releases.

Features

  • The model can estimate the effects of simple elevated terrain on maximum concentrations
  • It can estimate 24-hour average concentrations due to plume impaction in complex terrain using the VALLEY model 24-hour screening procedure.
  • Simple area sources can be modeled using a numerical integration approach.
  • It can model the effects of simple volume sources using a virtual point source procedure. The area and volume source algorithms are described in Volume II of the ISC model user`s guide (EPA, 1995b).
  • It can also calculate the maximum concentration at any number of user-specified distances in flat or elevated simple terrain, including distances out to 100km for long-range transport.
  • The program is fully compatible with EPA Screen3 model.
