BREEZE AERMOD SUITE, the next generation air quality modeling system. AERMOD is used to assess the impact of air emissions from a variety of industrial sources. The model predicts pollutant concentrations from point, line, area, volume, and flare sources with variable emissions in terrain from flat to complex.

Breeze Aeromod Suite

AERMOD captures the essential atmospheric physical processes and provides reasonable estimates over a wide range of meteorological conditions and modeling scenarios.

This state-of-the-science dispersion modeling system includes:

Productivity Tools for Data Input:

BREEZE AERMET is a meteorological preprocessor that computes boundary layer parameters for use with AERMOD. It is available in two version, AERMET Lite and AERMET Pro. AERMET Lite is included with the AERMOD SUITE and processes meteorological data already processed through stages 1 and 2 of AERMET Pro. This Lite version generates model ready AERMOD meteorological data files. You must already have the appropriate merged files for use as input.

BREEZE AERMAP is a terrain preprocessor designed to simplify and standardize the input of terrain data for AERMOD. Input data include receptor terrain elevation data. The terrain data may be in the form of digital terrain data that is available from the US Geological Survey or the U.K. Ordnance Survey. Output includes, for each receptor, location and height scale, which are elevations used for the computation of air flow around hills.

Productivity Tools for Analysis:

BPIP is a free Add-In to ISC and AERMOD Suites It performs direction specific building dimension calculations for use with the ISCST3 and AERMOD models to account for building downwash. Determining these values by hand can be a time consuming task. This wholly integrated tool makes it easy to analyze source and building data quickly and consistently, with a minimum of input information.

BREEZE GRAPHICS is an add-in that provides a seamless interface between BREEZE (both ISC and AERMOD) and Surfer for Windows. The software makes it easy to overlay source, building, receptor, and property line data on 2-D and 3-D graphics of model results. With GRAPHICS, you can create effective 2-D and 3-D graphics with a few mouse clicks.

WINDROSE is a versatile tool for understanding the effects of input meteorological data on downwind transport of pollutants from an industrial source. It can also be used to determine whether data from two or more sites are representative or suitable for modeling. Other applications include performing culpability analysis, siting monitoring instrumentation, and probabilistic analysis.

BREEZE METVIEW allows you to view, edit, and create model ready meteorological data. This add-in is included with BREEZE ISC and AERMOD SUITE

BREEZE OLM (Ozone Limiting Method) creates ozone concentration files for use in the BREEZE ISCST3 and AERMOD models to compute NO2 concentrations. This add-ins is included with BREEZE ISC and AERMOD SUITE.

PERCENT is a valuable tool to determine percentile concentrations for comparison to air quality standards. International air quality standards are often expressed as percentile values. In order to demonstrate compliance with these standards, you must determine the maximum concentration of a pollutant from all receptors at a specific percentile and averaging period.

BREEZE RUNAVG (Run Average) allows you to perform running average calculations based upon computed values instead of only "block" averages. This add-in is included with BREEZE ISC and AERMOD SUITE.
