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.
