CALPUFF is a multi-layer, multi-species non-steady-state puff dispersion model which simulates the effects of time- and space-varying meteorological conditions on pollution transport, transformation, and removal. It includes algorithms for subgrid scale effects and longer range effects. It can be applied for long-range transport and for complex terrain. The CALPUFF modeling system is an important tool for regional haze (visibility) and fine particulate matter (e.g., PM2.5) impact assessments over distances hundreds of kilometers from emission sources and also applies for certain near-field applications involving complex meteorological conditions.
BREEZE CALPUFF offers a complete user
graphical interface for the U.S. EPA-approved Version 5 and the advanced Version
6 of the CALPUFF modeling system, which includes:
- CALMET - a
diagnostic 3-dimensional meteorological model
- CALPUFF - an air quality
- CALPOST - a post-processing package
- Pre- and post-processors
BREEZE CALPUFF provides modelers with the
tools and functionality required to perform air quality analyses that help to
address both permitting, regulatory, and nuisance issues as well as perform
CALPUFF is an advanced non-steady-state meteorological and air quality modeling system developed by ASG scientists. It is maintained by the model developers and distributed by Exponent. The model has been adopted by the 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.
