CALPUFF is an advanced non-steady-state meteorological and air quality modeling system. The model has been adopted by the U.S. Environmental Protection Agency (U.S. EPA) in its Guideline on Air Quality Models as the preferred model for assessing long range transport of pollutants and their impacts on Federal Class I areas and on a case-by-case basis for certain near-field applications involving complex meteorological conditions. The modeling system consists of three main components and a set of preprocessing and post processing programs. The main components of the modeling system are CALMET (a diagnostic 3-dimensional meteorological model), CALPUFF (an air quality dispersion model), and CALPOST (a post processing package). Each of these programs has a graphical user interface (GUI).
The CALPUFF model simulates the effects of time and space-varying meteorological conditions on pollution transport, transformation and removal.

This paper summarises a study carried out for Carter Holt Harvey at Kinleith Pulp and Paper Mill (Tokoroa, New Zealand) which compared two different types of atmospheric dispersion model with actual ambient monitoring data for SO2. One of these models is CALPUFF.
