Gaussian Diffusion Models and Their Implementation using EPA's Recommended Software Technical Report # USPMPCS4900301. Student: Joseph Jerolimo, BS Environmental Science, 4th year undergraduate. Course: CS 490  Special Topics in Computer Science (Environmental Policy Modeling & Simulation – Air Quality Models). Spring 2003. There exist a number of models and algorithms, which were developed to model
air pollution concentration. Gaussian diffusion models, the most widely used
technique for modeling nonreactive pollutants. Real calculations based on
number of variables such as chemical transformations, atmospheric deposition,
and a number of source parameters such as area, point, line, plume, puff, and
meteorological parameters, turbulence, mixing height, and building downwash. In
this project the student analyzed some air quality models recommended by US EPA
and explored actual calculations of air pollutions using special US EPA
software. Pages 16, Figures 7, References 8
