AERMOD is the state-of-the-science, steady-state Gaussian air dispersion model that is EPA-approved for most refined modeling scenarios. 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 permitting, regulatory, and nuisance issues, perform academic research, and assist companies worldwide with capital planning. BREEZE AERMOD 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.
Download the tech sheetTo 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 are additions to implement parallel features. The applications run the exact algorithms but on different processors. There are two... Learn more
Assigning the model ready historical meteorological data in BREEZE AERMOD is easy. Simply select the files to use with a particular scenario. BREEZE will identify the period that the data set is valid for and display the station ID so that there are no mistakes setting up the input file. BREEZE MetView, a companion product, interprets model results from the meteorological point of view. Learn more
BREEZE AERMOD allows you to model the standard U.S. EPA sources (i.e., point, area, volume, open pit and EPA area line) and exclusive BREEZE sources such as flare and BREEZE area line sources. In addition, BREEZE offers object array generators that create user defined arrays (e.g., polylines, polygons, and Cartesian grids) of the model object type. Source elevations can also be processed with the embedded U.S. EPA AERMAP program. Learn more
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 Prime program.

Receptors are locations where BREEZE AERMOD will compute a concentration or deposition value. At least one receptor must be defined. Receptor elevations can also be processed with the embedded U.S. EPA AERMAP program. Learn more

BREEZE AERMOD suite includes the Industrial Source Complex (ISC) short-term model. ISC predicts pollutant concentrations from nearly any type of source emitting non-reactive pollutants. It allows you to define receptor grids and consider topographical features for each receptor location. You are also able to input above ground-level heights to simulate the impact at elevated or “flagpole” receptors. BREEZE ISC also predicts pollutant concentrations from: point, line, area, volume, and flare... Learn more
