BREEZE® ISC SUITE is a sophisticated air quality modeling system with an integrated GIS. BREEZE modeling systems go well beyond the capabilities of the standard U.S. EPA versions to include modeling of nearly any source type (including flare and line sources not found in the EPAs) in any type of terrain.

Breeze ISC Suite BREEZE ISC SUITE encompasses our most powerful air dispersion modeling software and tools into one easy-to-use 32-bit Windows® package. It includes the Industrial Source Complex (ISC) short-term model to predict pollutant concentrations from nearly any type of source emitting non-reactive pollutants.

ISCST3 applies to user-specified locations for source and receptor locations. ISC SUITE allows you to evaluate topographical features for each receptor model and input height above ground level when necessary to simulate impact at elevated or "flag pole" receptors.

ISC SUITE is a Geographic Information System (GIs) that enables modeled objects and results to interact and be displayed with a variety of geophysical data. The enhanced 32-bit version also allows for integrated contouring that creates contours as a layer within the system.

Productivity Tools for Analysis included with SUITE:

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.

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.

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.
