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).

CALPUFF View - Automated Coastline Download
One feature of the CALPUFF model is the ability to depict coastal interaction effects. Since the land surface can heat more rapidly than adjoining water, a Thermal Internal Boundary Layer (TIBL) can form and bring elevated source plumes close to the ground. This sets up a potential coastal fumigation scenario, which is illustrated in the figure below.
