The American Meteorological Society/Environmental Protection Agency Regulatory Model Improvement Committee (AERMIC) was formed to introduce state-of-the-art modeling concepts into the EPA's air quality models. Through AERMIC, a modeling system, AERMOD, was introduced that incorporated air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of both surface and elevated sources, and both simple and complex terrain.

AMS/EPA Regulatory Model (AERMOD) is a steady-state plume model. It is designed to apply to source releases and meteorological conditions that can be assumed to be steady over individual modeling periods (typically one hour or less). AERMOD has been designed to handle the computation of pollutant impacts in both flat and complex terrain within the same modeling framework. In fact, with the AERMOD structure, there is no need for the specification of terrain type (flat, simple, or complex) relative to stack height since receptors at all elevations are handled with the same general methodology. To define the form of the AERMOD concentration equations, it is necessary to simultaneously discuss the handling of terrain.

AERMET is an input data processor that is one of the regulatory components of the AERMOD modeling system. It incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts.


Meteorological Parameters

Surface meteorological data at project site will be collected for one season. The hourly meteorological data will be considered during the period are:

  • Wind speed and Direction;
  • Ambient atmospheric temperature;
  • Cloud cover;
  • Solar insolation;
  • Humidity.

Following parameters are considered for dispersion modeling:

  • Quantity of fuel;
  • Emission rate of pollutants
  • Stack:
  • Quantity of fuel;
  • Emission rate of pollutants
  • Stack:
