AERMOD View - Onsite Data in AERMET - Part 1: Formatting
AERMET – the meteorological pre-processor for the AERMOD modeling system – allows users to input their own custom meteorological data via its Onsite Pathway. This produces a highly representative dataset when using observations recorded at the site that will be modeled in AERMOD. One of the biggest challenges to this approach is that the modeler is responsible for identifying the variables and input format to AERMET. AERMET has two separate format specifications which can be utilized.

AERMOD View - Importing Gas & Particle Data
In addition to calculating air concentrations of pollutants, the AERMOD air dispersion model can calculate deposition fluxes from both particulate and gaseous emissions. When these routines are enabled, deposition parameters must be input to the model.

AERMOD View - Setting Stack Orientation
Air dispersion models typically have a variety of source types that can be used to represent sources of emissions. One of the most common source types is the point or stack release. Characterized by a well-defined exhaust point with buoyancy (via a defined exit temperature) and vertical momentum (calculated using the diameter of the release point and exit velocity), the point source is probably the most common source type employed in air dispersion modeling.
