Modeling Tips

CALPUFF View - Defining Receptors in CALPOST

The CALPUFF model allows users to specify receptors in two different formats:

1. Gridded Receptors are defined as the Sampling Grid in which receptor locations are defined by the Meteorological Grid dimensions and extents.
2. Discrete Receptors are located based on user-defined coordinates for each individual receptor.

AERSCREEN View - Understanding AERSCREEN Results

The AERSCREEN model estimates worst-case impacts of ground-level concentrations for a single source by interfacing with the screening mode built into the AERMOD executable. AERSCREEN produces several different output files which can be assessed and analyzed using the advanced output viewer of Lakes Software’s AERSCREEN View application.

AERMOD View - Graphical Options: Using Layouts

As we have discussed in this space before, presenting high-quality graphical depictions of air dispersion modeling output is vital to communicating the meaning of the calculations. The Graphical Options within Lakes Software’s wide range of commercial products give users the customization options that modelers need. These options are accessed via buttons on either the main toolbar or Annotation Toolbar.
