BREEZE AERMOD is loaded with features that optimize your modeling. Although there are numerous options, the intuitive user interface is extremely easy to learn and understand. As a Microsoft Certified Partner, BREEZE conforms to design guidelines for products specifically developed for the Microsoft® Windows operating system. Significant effort has gone into giving users the option to hide many of the data entry options that they might not require. For example, if you are not modeling deposition, you can choose not to show the data entry options related to deposition. This is extremely beneficial to new users or users who model infrequently.
The features that go into BREEZE products are given careful consideration so that only those that provide real value to the user are present. Many other companies rely on BREEZE software to define their own set of features. Our joint application design sessions involve people who actually use the products from different industries, government, and academia.
BREEZE AERMOD is available in three levels of functionality:
- Standard (FREE)
- Professional (Pro)

Modelers don't want a modeling system that is more trouble than it's worth. They want a system that is backed by expert technical support, a large user community, and is compatible with the latest Microsoft operating systems.
The smart, friendly air dispersion modeling system.
Some call BREEZE AERMOD the world's smartest air dispersion modeling system. Why? Because it adapts to your workflow, not the other way around. Here's is the general data entry flow for BREEZE AERMOD.
Click on an icon for more information.

Without a doubt, BREEZE AERMOD offers you 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. BREEZE AERMOD provides new and seasoned modelers with the tools and functionality required to perform air quality analyses that help to address both permitting / regulatory and nuisance issues.
BREEZE developers have been developing user-friendly graphical user interfaces longer than any other modeling software provider. In fact, BREEZE revolutionized the air modeling industry over 25 years ago when we first introduced commercial software designed to enhance modeler productivity. It is used by regulatory agencies around the world and is a key component of the U.S. Department of Defense's modeling analysis command center (MACC).
Once you experience BREEZE software, you'll see why we are the world leader in providing robust, intuitive, user-friendly modeling applications.
BREEZE AERMOD integrates with 3DAnalyst to perform the post model run analysis and visualization of results. There is an incredible amount of flexibility that you have with 3DAnalyst. No other product gives you such insight into the data generated by the AERMOD model.
BREEZE AERMOD is available in three editions: Standard, Pro, and Pro Plus. Each edition has varying levels of functionality. For more details on the specific level of functionality each edition provides, please view the Feature Matrix section.
The following are examples of results generated by BREEZE AERMOD using 3DAnalyst.
Robust, automated contouring
Automatically create contours depicting pollutant concentrations. Let BREEZE define the contour levels or define specific levels for each pollutant. Display results in Google Earth and Surfer.
- Created contours depicting differences between different model scenarios or model versions.
- Blank out contours within the perimeter of the plant boundary
- Choose different levels of transparency
Display results as a function of time
BREEZE AERMOD allows you to view modeled concentraitons as a function of time. Simple select the data set to chart and instantly, each receptor's concentration is available for viewing as a function of time. You can select recepotors from either a drop down list or by clicking on the receptor in the Map display.
Perform source culpability analyses
BREEZE makes it easy to graphically display the contribution various sources or facilities contribute to receptors. Results can be displayed in chart or table format. Tablular data can be copied and pasted to spreadsheets and other applications.
Create movies of concentrations over time
Creating movies of your time series data is a snap. Never before has it been so easy and so fast to create .AVI and Flash movies for use in presentations.
Animations can be made of the 2D, 3D, and Cross Section display views.

Perform Radius of Influence Analysis
Determine NAAQS radius of influence analysis by selecting a location on the base map and having BREEZE determine the radial extent of a scenarios impact for user defined source groups and averaging periods. Graphically display the results and save the image or copy it to another application.
