Modeling Software for EH&S Professionals

AERMOD is a steady-state Gaussian dispersion model that represents the current state-of-science and promulgated dispersion model from the U.S. EPA. BREEZE AERMOD is an enhanced version of the EPA-approved AERMOD that 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. BREEZE AERMOD/ISC offers the most complete air quality modeling system available on the market today. No other application is used by more air quality professionals around the world.

Key Features
  • Integrates the most recent U.S. EPA AERMOD version 14134, released on May 16, 2014, including high-speed parallel and BREEZE-enhanced versions of the new executable
  • Includes a basic, merge-only version of BREEZE AERMET and a basic version of BREEZE MetView
  • Streamlined graphical user interface for more intuitive and easier dispersion modeling
  • Streamlines NO2, SO2 and PM2.5 modeling for U.S. NAAQS
  • Incorporates the Ambient Ratio Method (ARM) and ARM2 for NO2 modeling
  • Models an unlimited number of sources and receptors
  • Models numerous source types including point / stack (vertical, horizontal and capped), area, volume, open pit, flare, BREEZE area line and EPA area line
  • Models numerous receptor types including discrete Cartesian grid, polar grid, and variable density grid
Product Tour

U.S. EPA AERMOD incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of both surface and elevated sources, and both simple and complex terrain. There are two regulatory components of EPA’s AERMOD:

  • AERMET - a meteorological data preprocessor (available as a separate BREEZE application)
  • AERMAP - a terrain data preprocessor (embedded in BREEZE AERMOD)

 

Non-regulatory components of EPA’s AERMOD include:

  • AERSCREEN - a screening version of AERMOD (available as a separate BREEZE application)
  • AERSURFACE - a surface characteristics preprocessor
  • BPIPPRIME - a multi-building dimensions program that incorporates the GEP technical procedures for PRIME applications (embedded in BREEZE AERMOD)

 

BREEZE AERMOD enhances these basic EPA programs providing modelers with more functionality and tools for analyzing results.

Parallel Processing

To combat the increased runtimes observed with EPA’s AERMOD, BREEZE created a parallel processing version to slash runtimes through the use of a distributed computer network (cluster) or multi-CPU environment. Our high performance applications produce pollutant concentration estimates identical to EPA’s Fortran executable. The only code changes to the application ... ::  learn more...

Buildings
AERMOD takes into account the obstruction of wind flow from structures, such as buildings and point sources (i.e., stacks). Like any other model object in BREEZE AERMOD, buildings can be copied and pasted or drawn into the 2D display. Building information can be processed with the embedded U.S. EPA BPIP ... ::  learn more...
