AERMOD Pro

BREEZE AERMOD Pro is loaded with features to optimize your modeling. The intuitive user interface is extremely easy to learn and understand, and guides users through the model setup and analyzing results. With BREEZE AERMOD Pro, users have access to a variety of displays (e.g., 3D view, time series view, etc.), data entry options (e.g., importing a base map, copying and pasting to a table from Excel, CAD drawing tools), data processing options, model outputs, and plotting and data manipulation/analysis tools. Additionally, 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. These advanced features included in BREEZE AERMOD Pro are very beneficial for new and seasoned users, and increase productivity by adapting to the users preferences and workflow.

A basic, merge-only version of BREEZE AERMET and a basic version of BREEZE MetView come standard with BREEZE AERMOD Pro.

Price: $1,495.00

AERMOD Pro Plus

BREEZE AERMOD Pro Plus includes all of the features of the Pro edition, as well as a handful of additional features mainly pertaining to data manipulation/analysis and animation graphics. For example, BREEZE AERMOD Pro Plus provides users with a distribution view and a contribution view option, which users can utilize to determine the distribution and contribution of each source over a given time period. Additionally, with BREEZE AERMOD Pro Plus, users have the ability to create a variety of animations (e.g., map, 3D, cross-section, contribution chart, distribution chart, and Google Earth contour animation) that they would not have access to with the Pro edition. These animations are great visual tools when presenting results to colleagues or clients. Other enhanced performance features that are included in the Pro Plus edition but not the Pro edition include the ability for users to:

  • Export to Shapefiles
  • Plot to scalable vector graphics
  • Combine multiple post-processed POST files into a single file
  • Merge plot files
  • Merge post files
  • Export data to XYZC, VTK, and XYC formats
  • Interpolate dynamic inter-node
  • Create a data flowchart

A basic, merge-only version of BREEZE AERMET and a basic version of BREEZE MetView come standard with BREEZE AERMOD Pro Plus.

Price: $1,995.00

BREEZE AERMOD/ISC is available in two editions: Pro and Pro Plus. BREEZE AERMOD Pro is suitable to conduct complete full air dispersion modeling analyses and reporting. The Pro Plus edition offers additional features and functionality to increase efficiency as well as advanced post-processing and results tools.

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 are additions to implement parallel features. The applications run the exact algorithms but on different processors.

There are two deployment options available for BREEZE AERMOD to users interested in parallel processing— local and remote resources. A two-core local parallel processing version is included in BREEZE AERMOD.

Local

The local approach involves purchasing parallel software and determining how many processors are desired to run the software application. Improvements in the product’s performance enhancements are based directly on the number of CPUs (or cores) utilized. If a new octo-core computer is not in the budget, a computer cluster can simulate a single multi-core computer.

Remote

Alternatively, the BREEZE Remote Modeling System requires no proprietary software and runs on a massively parallel computer cluster managed by BREEZE Software. Users upload input files anytime (24/7), receive email notifications when model results are completed, and slash model runtimes up to 100 times faster!

U.S. EPA Equivalency

BREEZE developed AERMOD Parallel to significantly improve performance across multiple processors. As part of the product development process, equivalency testing was performed with hundreds of AERMOD model runs using both the AERMOD Fortran executable and the BREEZE AERMOD Parallel executables. Based on all completed test cases, modeling results generated by the BREEZE AERMOD Parallel are identical to those generated by the U.S. EPA AERMOD executables.
