The ISC-AERMOD View interface includes all the ISCST3 modeling options in addition to the following:
- Graphical input where you can use your mouse to graphically define the location of stacks, receptor grids, discrete receptors, and plant boundary.
- Converts your Cartesian and polar receptor grids into discrete receptors with the option of automatic elimination of receptors within your plant boundary.
- Extracts digital terrain heights for receptor elevations from 1 degree and 7.5 minute USGS Digital Elevation Models (DEMs), UK NTF and DTM, and XYZ
formats.
- Automatic creation of your terrain grid file for dry depletion analysis in elevated or complex terrain using DEMs.
- ISC-AERMOD View User's Guide uses pictures and graphical information to assist you in quickly grasping the manual's contents.
- 3D visualization of your buildings and stacks with true 3D control and the ability to apply any texture to building surfaces.
- The program checks valid ranges for all entry fields which will help save you time by preventing wrong entries.
- You can view all the sources and receptors you have defined for your modeling project graphically in context with one or more site maps (in AutoCAD DXF,
USGS DLG, LULC, BMP and Shapefile formats).
- Before running your project, ISC-AERMOD View displays a report of all options selected along with a list of any missing information.
- Powerful postprocessor with overlay site-maps in AutoCAD DXF format, USGS DLG and LULC maps, Shapefile and Bitmap images, and automated
"no-hassle" shaded contour plots. You can have multiple plots displayed at the same time on the screen. ISC-AERMOD View can also export your modeling results to Surfer.
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.
