In the report, a comparison is made of two different dispersion models, CALPUFF and ISC3. CALPUFF is a Lagrangian puff model which simulates continuous puffs of pollutants released into the ambient flow, whereas ISC3 is a Gaussian plume model that treats emissions from a source as a contiguous mass. CALPUFF may be configured to treat emissions as integrated puffs or as slugs. ISC3 is currently recommended for routine use in assessing source impacts involving transport distances of less than 50km. The report is being released to establish part of the basis for review of the consequences resulting from use of CALPUFF in routine dispersion modeling of air pollution impacts.
