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. The U.S. EPA recommends its use for regulatory applications on scales of tens to hundreds of kilometers.
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 dispersion model
- 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 academic research.
- Supports the U.S. EPA recently approved CALPOST 6.221
- Streamlines visibility post-processing
- Supports the U.S. EPA-approved Version 5.8 and the advanced Version 6 models
- Integrates with the BREEZE 3DAnalyst
- Models an unlimited number of sources and receptors
- Models numerous source types including point, area, volume, buoyant line, and non-buoyant line
- Models numerous receptor types including discrete Cartesian grid, polar grid, and variable density grid
