Part of Air quality modelling

We recommend using the following models to predict ground level concentration of pollutants.

For specific details on dispersion modelling, see the Air Quality Modelling guideline.

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.
Refined Assessment	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.
