Detailed Description

AERMOD View

AERMOD View





AERMOD View Introduction

AERMOD View is a complete and powerful air dispersion modeling package which seamlessly incorporates the popular U.S. EPA models into one interface: AERMOD, ISCST3, and ISC-PRIME. These models are used extensively to assess pollution concentration and deposition from a wide variety of sources.

AERMOD is the next generation air dispersion model designed for short-range (up to 50 kilometers) dispersion of air pollutant emissions from stationary industrial sources.. AERMOD is a steady-state plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling, including treatment of both surface and elevated sources, and both simple and complex terrain


Aermod View Features

Integrated Graphical User Interface
Fully integrated interface combining easy to use graphical tools (e.g., sources, buildings, and receptors), seamless model run, and automated contouring and posting of results.

Powerful 3D Visualization
Complete 3D visualization of your entire modeling area. Sources, buildings, and concentration and/or deposition contour results are displayed in context with the surrounding terrain.

Export to Google Earthâ„¢
This exciting feature allows you to export your buildings, sources, receptors and contours into Google Earth giving you a more realistic image of where your pollutants will impact surrounding areas.

New Project Wizard
The New Project Wizard allows you to quickly and easily set up a new project in AERMOD View. You can setup your project by specifying a reference point in Latitude/Longitude, UTM, or any other local coordinate system.

AERMOD Parallel at No Extra Cost
Included in the package, at no extra cost, is AERMOD MPI, Lakes Environmental parallel version of AERMOD. This will significantly cut down on model run times, while still giving the high quality results you expect from AERMOD View.

Professional Printing Templates
Take advantage of the ready-to-use printout template. You can include your company logo, project number, and other project specific information.

Multi-Chemical Utility
This utility will boost your productivity drastically by allowing you to specify emissions from several pollutants emitted by the same source. No need to setup different projects for each pollutant!

Terrain Processor with Automatic Downloads
Advanced terrain processing capabilities are offered for several terrain data file formats such as NED, SRTM, and USGS DEM. Automated download of terrain data files from webGIS. SRTM3 Terrain data at 90 m resolution available worldwide.

Complete Meteorological Pre-Processors
Several tools are available for easy processing of meteorological data for AERMOD and ISC models.

The AERSURFACE utility allows you to automatically calculate the required surface characteristics.

U.S. EPA NO2 NAAQS Tool
The U.S. EPA hourly National Ambient Air Quality Standard for NO2 is not calculated directly by the AERMOD model, however, AERMOD View includes an easy-to-use tool which will quickly calculate these values.
