- Feb 13, 2018 The modeling system consists of three main components and a set of preprocessing and postprocessing programs. The main components of the modeling system are CALMET (a diagnostic 3-dimensional meteorological model), CALPUFF (an air quality dispersion model), and CALPOST (a postprocessing package).
- Air dispersion modeling provides a visual mathematical simulation of how air pollutants disperse in the ambient atmosphere. Based on emissions source and meteorological data as well as topography information, a dispersion model calculates an estimate of the downwind concentration of pollutants as they travel away from emissions sources.
Air Dispersion Modelling
AERMOD View Introduction AERMOD View is a complete and powerful air dispersion modeling package which seamlessly incorporates the popular U.S. EPA models into one interface: AERMOD, ISCST3, and ISC-PRIME. These models are used extensively to assess pollution concentration and deposition from a wide variety of sources. AERMOD is the next generation air dispersion model designed for short-range (up to 50 kilometers) dispersion of air pollutant emissions from stationary industrial sources. AERMOD is a steady-state plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling, including treatment of both surface and elevated sources, and both simple and complex terrain | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

This project is comprised of three tools for use with the AERMOD dispersion model: 1. SHARP: The Sub-Hourly AERMOD Run Procedure allows the user to run AERMOD using fine-resolution meteorology. DISTANCE: The DISTANCEDEBUG tool provides additional output that can be used to diagnose causes for high concentrations.
