CALPUFF is a multi-layer, multi-species non-steady-state Lagrangian puff dispersion model recommended by the EPA for regulatory applications from tens to hundreds of kilometers. BREEZE CALPUFF provides a graphical user interface and productivity tools for CALPUFF and its meteorological and post-processing components. BREEZE 3D Analyst enables users to analyze and visualize modeling results in 2D and 3D, including contour plots, isosurfaces, and animations for presentations.
BREEZE CALPUFF Tech Sheet
- 1. Continuous Release Modeling Software for EHS Professionals CALPUFF is a multi-layer,multi-species non-steady-state Lagrangian puff dispersion model,which simulates the effects of time-and space-varying meteorological conditions on pollution transport,transformation,and removal. It includes algorithms for sub grid 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 and productivity enhancements for the U.S.EPA-approved CALPUFF modeling system,which supports: CALMET –a diagnostic 3-dimensional meteorological model (that considers coastal effects,slope flows,kinematic terrain effects,terrain blocking effects,and a divergence minimization procedure) and a micro-meteorological model for overland and overwater boundary layers CALPOST –a post-processing package that computes time- averaged concentrations,deposition fluxes,and visibilityimpacts Numerous pre-and post-processors: • READ62 • SMERGE • PMERGE • MAKEGEO • CALSUM • APPEND • POSTUTIL Features for Enhanced Productivity BREEZE CALPUFF improves productivity by offering users many advantages that result in seamless,time-efficient modeling runs. The careful design streamlines 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. Building Profile Input Program (BPIP) -integrated BPIP utility automatically calculates building heights and projected building widths for simple,multi-tiered,and group structures Coordinate Conversion -input projections can be converted to other systems,such as latitude/longitude coordinates to UTM or Lambert Conformal coordinates Object Visualization -results and objects are easily visualized using the latest Windows-based technology User-Friendly Interface -easy-to-use toolbars and recognizable icons allow easy navigation throughout the application Undo Feature -undo recent actions 3DView -view buildings and terrain in three dimensions Multi-WindowView -view up to four windows simultaneously to compare graphical and text-based results Data Explorer -view project data in a spreadsheet view, allowing users to copy and paste directly from Microsoft Excel®,sort and edit data,and filter objects by data types Data Downloads -link to databases containing meteorological, terrain,and land use data Map Tab -import DXF file,shape file,or base map image to visualize model objects CALPUFF BREEZE CALPUFF provides modelers with the tools and fuctionality to analyze and visualize modeling results.

It is useful for analyzing meteorological, terrain,and concentration data. Animated movies can be created for display in presentations and it is compatible with Golden Software's Surfer® application and Google Earth™. Plotting The plotting and graphing features in 3D Analyst allow you to create impressive plots of modeling results and input datasets so that you can quickly analyze the data in both two and three dimensions. With BREEZE 3D Analyst,you can: • Create custom contour levels for an entire project or individual datasets • Customize all object properties to display only the results and objects you want to see • View data from every angle with 2D plane views,3D surfaces,and slices of 3D data in the XY,XZ,and YZ planes • Plot data as a function of time and animate the time steps • Use your mouse to view real-time data interpolation between receptors • Plot data to Golden Software's Surfer application and Google Earth • Create 3D templates that can be loaded with future projects to quickly recreate three dimensional display views Data Manipulation Not only can you display data,BREEZE 3D Analyst allows users to perform data manipulation simultaneously. Temporarily transform data with easy-to-use scaling and transformation tools to analyze how your results could change. You can also use the numerous tools to extract averages,percentiles,highs, and more,all from a single dataset. The BREEZE team of modelers,meteorologists,scientific software specialists,and PhDs are available to assist you with the science behind the software.
