AERMOD View - Customize Output Units
The AERMOD model features default units for emission inputs and concentration or deposition outputs. Emissions are presented as grams per second (g/s)*, and concentrations are calculated as micrograms per cubic meter (µg/m3). However, there may come a time when one or both of these default units needs to be changed to better represent project data. This change can be easily made via the Source Pathway options.

AERMOD View - Posting Concentrations
Displaying model output is an integral part of air dispersion modeling. Concentration contour plots help modelers quickly identify trends and high concentrations from modeling projects. AERMOD View includes numerous visualization options to make the modeler’s job even easier.

CALPUFF View - Modeling Roads
The CALPUFF modeling system does not feature a native source type for mobile sources (e.g., vehicles). One way to treat these emissions in the model is to calculate the cumulative emissions of all vehicles which drive on a road and parameterize the road itself into the model as the source. With the introduction of CALPUFF’s Version 7 Modeling System and the release of CALPUFF View Version 8.2.0, users have a few options as to how to model these sources in CALPUFF.
