You can graphically define the location of your sources, discrete receptors, receptor grids, plant boundary and more!

3D visualization of your stacks and buildings. True 3D control allows you to view your site from any perspective. You can select any texture and apply it to your buildings.

ISC-AERMOD View has a unique powerful postprocessor with overlay site-maps in various file formats (AutoCAD DXF file, USGS DLG and LULC maps, and Bitmap images) and automated "no-hassle" color contour plots. One or more contour plot files can be displayed on the screen at the same time. High-quality graphical output can be sent to a printer or pasted into your word processor document.

ISC-AERMOD View extracts digital terrain heights for receptor elevations from 1-degree and 7.5-minute Digital Elevation Models (DEMs), UK NTF and DTM, and XYZ formats.

ISC-AERMOD View Introduction

ISC-AERMOD View is a complete and powerful Windows air dispersion modeling system which seamlessly incorporates three popular U.S. EPA models into one interface: ISCST3, AERMOD and ISC PRIME.

The Industrial Source Complex - Short Term regulatory air dispersion model (ISCST3) is a Gaussian plume model and is widely used to assess pollution concentration and/or deposition flux on receptors from a wide variety of sources.

AERMOD is the next generation air dispersion model which incorporates planetary boundary layer concepts. Further information about this model can be found by clicking here.

The Industrial Source Complex - Plume RIse Model Enhancements (ISC-PRIME) dispersion model is similar to the ISCST3 model but contains enhanced building downwash analysis.

ISTSC3 Modeling Capabilities

The ISC-AERMOD View interface includes all the ISCST3 modeling options in addition to the following:

ISC-AERMOD View Input Requirements

The ISC-AERMOD View interface uses the five pathways that compose the ISCST3 runstream file as the basis for its functional organization. These pathways are:

Control Pathway (CO): where you specify the modeling scenario and the overall control of the modeling run.

Source Pathway (SO): where you define the sources of pollutant emissions. In this pathway you must specify the location of the source and source parameters, i.e., emission rate, physical stack height, stack gas exit velocity, etc. Optional inputs include: source elevation, building dimensions, variable emission rates, particle size distributions, scavenging coefficients, etc.

Receptor Pathway (RE): where you define the receptors to determine the air quality impact at specific locations. Input requirements are the location and optional ground elevation for each receptor.

Meteorology Pathway (ME): where you define the atmospheric conditions of the area being modeled so that it can be taken into account when determining the distribution of air pollution impacts for the area. ISCST3 requires hourly surface weather data that can be preprocessed by Rammet View which comes FREE with the ISC-AERMOD View package.

Terrain Grid Pathway (TG): where you have the option of specifying gridded terrain data to be used in calculating dry depletion in an elevated or complex terrain.

Output Pathway (OU): where you define which output results are necessary to meet the needs of the air quality modeling analyses. Various types of output files can be produced. You may choose to output concentration, dry deposition flux, wet deposition flux or total deposition flux. ISC-AERMOD View comes with a postprocessor that can plot these results for you automatically.

ISC-AERMOD View Support Packages: BPIP View and Rammet View (Included)

BPIP View - Interface for the EPA Building Profile Input Program (BPIP)

BPIP View is a graphical interface to speed up the work load involved in setting up input data for the U.S. EPA's BPIP model (Building Profile Input Program). The BPIP model calculates direction-specific building widths and building heights for use with the ISC model in downwash analyses. BPIP View is a true, native Microsoft Windows application and runs in Windows 3.1, Windows 3.11 (Windows for Workgroups), Windows 95, and Windows NT.

Additional features are:

Rammet View - Interface for the EPA PCRAMMET Meteorological Preprocessor

Rammet View is a Windows interface for the U.S. EPA PCRAMMET meteorological preprocessor. PCRAMMET is used for processing National Weather Service (NWS) data for use in the EPA short term air quality dispersion models such as ISCST3.

Additional features are:
