TECHNICAL SPECIFICATIONS
AERSCREEN View is an interface for the AERSCREEN US EPA air dispersion model. See below technical specifications for this model:
| AERSCREEN | |
|---|---|
| Parameter | Description |
| Model Name | AERSCREEN |
| Developed By | United States Environmental Protection Agency (US EPA) |
| Model Type | Steady-state Gaussian plume screening-level air dispersion model (interfaces with the AERMOD model) |
| Range | Up to 50km from the source |
| Atmospheric Stability Model | Planetary boundary layer theory, turbulence scaling concepts |
| Release Types | Buoyant or neutrally buoyant plumes |
| Emissions Types | Constant or planned or fugitive |
| Atmospheric Chemistry | NOX to NO2 (OLM and PVMRM methods) |
| Source Types | Point, area, volume, flare* |
| Meteorology | Site-specific matrix of meteorological conditions generated by MAKEMET |
| Terrain | Flat or elevated terrain preprocessed by AERMAP model |
| Receptors | Automatically-generated receptor array out to user-defined maximum downwind distance and up to 10 discrete receptor distances |
| Other Options | Building downwash modeled by BPIP-PRIME |
| Regulatory Status | Preferred US EPA regulatory model for near-field applications |
