ISC PRO

BREEZE AERMOD/ISC Pro

BREEZE AERMOD/ISC Pro for Windows ® is a new generation air quality modeling system used to support both regulatory and non-regulatory modeling requirements worldwide. This application is used to assess the impact of air emissions from a variety of industrial sources and includes enhanced versions of both the AERMOD (with PRIME) and ISC dispersion models. These models predict pollutant concentrations from point, line, area, volume, and flare sources with variable emissions in all terrain regimes. BREEZE AERMOD/ISC Pro includes many new features designed to decrease model set-up time and streamline navigation.

Features Found in AERMOD/ISC Pro and AERMOD/ISC GIS Pro:

Modeling Wizard: Novice and expert modelers can follow a step-by-step process to set up and execute a modeling run.
Summary Reporting: View a detailed or abbreviated summary of model scenario input.
Multiple Contour Gridding Routines: Choose from 9 available gridding routines with Golden Software's Surfer ® . Immediate changes to gridding options make analyzing concentration results quick and easy.
Enhanced 3-D Window: Easy navigation combined with multi-layer display functionality in the 3-D view assures data quality and renders report-quality images of terrain relief, model objects, and concentration results.
"Navigate" Toolbar: One-click navigation combines controls for both 2-D and 3-D views. This increases productivity by allowing the user to control different perspectives with fewer mouse clicks.
Object Display Styles: View model objects in three different modes - solid, transparent, and wire frame. Simply change the viewing perspective to analyze building and source relationships.
DXF, Bitmaps, and Basemaps: Import bitmap and AutoCad ® .DXF files as basemaps to assist with model object placement or for other referencing purposes.
BREEZE Post-processor that outputs the concentration value of a user-specified percentile and averaging period.
BREEZE RUNAVG: Allows you to perform running average calculations rather than block averages only.
BREEZE BPIP (Building Profile Input Program): Pre-processor that calculates direction-specific building dimensions in order to analyze building downwash.
BREEZE OLM (Ozone Limiting Method): Creates ozone concentration files for use in the BREEZE ISCST3 and AERMOD model to compute NO 2 concentrations.

AERMOD

AERMOD is a state-of-the-science dispersion modeling system that simulates essential atmospheric physical processes and provides refined concentration estimates over a wide range of meteorological conditions and modeling scenarios.

AERMOD includes two data preprocessors for streamlining data input. AERMET, a meteorological preprocessor, computes boundary layer and other necessary parameters for use with AERMOD and accepts data from both on-site and off-site sources. AERMAP is a terrain preprocessor that simplifies the computation of receptor elevations and effective height scales for numerous types of digital data formats, including USGS 1 Degree and 7.5 minute digital elevation model (DEM) files and U.K. Ordnance Survey ® digital elevation data. ISC

The Industrial Source Complex (ISC) short-term model 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.
