BREEZE CALPUFF improves productivity by offering users many advantages. The careful design of this air dispersion model enables modelers to streamline all aspects from setup to model execution to results analysis. BREEZE CALPUFF saves you time and money by minimizing duplicate data entry and data entry mistakes. BREEZE's professional staff of modelers, meteorologists, scientific software specialists, and PhDs are available to assist you with the science behind the software.

Read the release notes for the full list of features and bug fixes

  • Supports Exponent's latest versions of the CALPUFF modeling system: CALPUFF Version 7.2.1, CALMET Version 6.5.0, CALPOST Version 7.1.0 and related processors
  • CALPUFF Version 7, which is incorporated in this latest version of BREEZE CALPUFF, introduces new source types such as roadways and flares
  • Enables the option to download high-resolution base maps for any location around the world, which can assure proper setup of model objects in the study domain and enhance graphical visualization
  • Incorporates a new tool to calculate hourly background ozone in CALPUFF
  • Incorporates a new tool to create and/or edit background files in CALPOST
  • Incorporates a new feature to activate or deactivate boundary receptors in CALPOST
  • Adds an Output Summary file for the following list files: TERREL and CTGPROC list file, READ62 list file, Coastline polygon file (to be used in CALPUFF), and Puff tracking file (available in CALPUFF Version 6.42)
  • Enables the capability of importing boundary receptors from AERMOD files with .ami, .inp, and .dat extensions
  • Replaces the sensitive receptor file with a CALPUFF control file in CALPOST so that the information is in one file rather than requiring both a sensitive receptor file and CALPUFF control file
  • Improves the efficiency of generating modeling results for sensitive receptors in CALPOST
  • Includes the implementation of various bug fixes
  • Supports the latest U.S. EPA-approved version of the CALPUFF modeling system: CALPUFF Version 5.8.5, CALMET Version 5.8.5 and CALPOST Version 6.221
  • Streamlines graphical user interface for more intuitive and easier dispersion modeling
  • Simplifies the setup of pre-modeling objects with a variety of utilities
  • Analyze post-modeling results with multiple tools including BREEZE 3D Analyst and the processing of sensitive receptors
  • Organizes model scenarios using a skeleton and neat file structure for better file management
  • Includes back compatibility with previous BREEZE CALPUFF projects
  • Integrates with the BREEZE 3D Analyst
  • Streamlines post-processing visibility
  • Models numerous source types including point, area, volume, and buoyant line
  • Models numerous receptor types including discrete Cartesian grid, polar grid, and variable density grid
  • Models buildings with integrated BPIP analysis and downwash
  • Imports buildings, sources, and receptors from ISC/AERMOD input files
  • Draw sources with CAD drawing tools
  • Supports 7.5 DEM and 1 minute USGS DEM
  • Supports three-dimensional meteorological fields as well as single station meteorology
  • Adds a feature to input parameters for the radiological decay option, a type of chemical transformation that can be modeled with CALPUFF version 6.42 or later
