AERMOD View - Output: When Did a High Value Occur?
Contour plots are one of the most common forms of output from air dispersion models. They are useful in quickly identifying trends and maxima, but they also require a careful eye to ensure proper interpretation.

AERMOD View - Long Term Averages
The AERMOD air dispersion model can calculate three different long-term averages: Month, Period, and Annual. The equation below demonstrates how these averages are calculated for a model run spanning a single year.

AERMOD View - Understanding AERMOD’s Profile Met File
The US EPA AERMOD air dispersion model requires two meteorological data files – a surface file (*.SFC) and a profile file (*.PFL). The profile met file is commonly misunderstood for a variety of reasons. That AERMET, the meteorological preprocessor for AERMOD, requires upper air data as input, implies that the profile file will contain some sort of record of this data for AERMOD to analyze. Some users may be confused to open a profile file only to find a limited amount of information from a single level of measurement.
