Alberta Environment and Parks recommends using the following models to predict ground level concentration of pollutants.

For specific details on dispersion modelling, see the Air Quality Model Guideline at:

All recommended models are approved by the United States Environmental Protection Agency (EPA):

Analysis Recommended Models
Screening AERSCREEN - Uses worst-case meteorological data
Refined Assessment AERMOD-PRIME -This is a multi-source steady-state plume model.
CALPUFF - This is a multi-layer, multi-species, non-steady-state puff dispersion model that can simulate the effects of time- and space-varying meteorological conditions.
