| Model Type | Steady-state Gaussian plume air dispersion model |
| Range | Up to 50km from the source |
| Atmospheric Stability Model | Planetary boundary layer theory, turbulence scaling concepts |
| Wind Field | Homogeneous |
| Release Types | Buoyant or neutrally buoyant plumes |
| Emissions Types | Constant or time-varying, planned or fugitive |
| Atmospheric Chemistry | NOX to NO2 and SO2 decay |
| Source Types | Point, area, volume, open pit, line*, flare* |
| Meteorology | Hourly surface and upper air data (processed by AERMET) Minimum Requirements for AERMOD Surface Meteorological Data File |
| Terrain | Flat or elevated (terrain processed by AERMAP) |
| Receptors | Several types of grids (Cartesian, polar) and discrete receptors |
| Other Options | Building downwash (modeled by BPIP-PRIME) |
| Regulatory Status | Preferred US EPA regulatory model for near-field applications |
