CALPUFF is a non-steady state puff dispersion model CALPUFF can account for three-dimensional time-varying wind fields in the atmosphere, wet and dry deposition, some chemical transformations and visibility reduction due to particulates in the atmosphere. This includes the effects on visibility due to fine particulates that are the result of chemical transformations. The CALPUFF System consists of the CALPUFF model, its meteorological preprocessor, CALMET, and several other preprocessors to prepare terrain and land cover data for use in CALPUFF. The CALPUFF system also includes a graphical user interface to facilitate its use.
