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.

Copying Projects in Lakes Software Applications
There are many reasons why it may be necessary to create a copy of a modeling project. You may want to make edits to a scenario without overwriting previous results, or you need to re-run the project using a different set of meteorological data while maintaining the rest of the inputs.

AERMOD View - EVENT Processing
When modeling with source groups in the AERMOD air dispersion model, it is not always obvious how much each sources contributes to a calculated concentration. To facilitate source contribution analysis, AERMOD includes routines called EVENT processing which analyze user-specified events (e.g., design concentrations, threshold violations) and print each source’s contribution to the event.
