AERMOD View - New ALPHA Options in AERMOD 22112
With the latest release of the AERMOD model dated 22112, the U.S. EPA has continued to expand the formulated capabilities of the model. Most of these updates have been added as ALPHA non-default options, a concept we covered in a previous modeling tip. AERMOD 22112 contains 6 new ALPHA options which are described below:

CALPUFF View - Parameter Limits
The CALPUFF modeling system is very sophisticated and supports a wide range of modeling scenarios. One limitation of the system is that there are finite numbers of objects that can be specified on the model input parameters. For example, CALPUFF can only accept a finite number of sources of each type in a single model run.

AERMOD View - Using Flagpole Receptors
Air dispersion models are only capable of calculating concentration at specific locations. These locations are called receptors. In the U.S. EPA’s AERMOD air dispersion model, concentration calculations at each receptor are done at the ground level as opposed to some height above ground. For this reason, output from the AERMOD model is often referred to as “Ground Level Concentrations” (GLCs).
