AERMOD View - Choosing Pollutants
As the preferred air dispersion model for analysis of air pollutant concentrations in the ambient environment up to 50-km, AERMOD is used for a wide variety of buoyant and neutrally-buoyant releases. One recurring question about AERMOD is what pollutants it can (or cannot) model. Coded into the model is a list of pollutant types used to identify the pollutant being modeled for a particular run.

AERMOD View - When Numerical Values Are Outside AERMOD’s Default Threshold
A standard model run using the AERMOD air dispersion model produces numerical output with up to 13 significant figures (e.g., xxxxxxxx.xxxxx). Projects which use very low or very high emission rates may run into a problem where the model outputs values which do not fit properly within this limit. For examples, concentration values of 1E9 units or higher will result in a field of asterisks written to the output file as shown below.

AERMOD View - Working with the Plots Tab
In a previous modeling tip, we provided an overview on working with layers within Lakes Environmental Software products. In the popular AERMOD View application, another tab is Plots which lists all available contour plot output files.
