Error Propagation In Air Dispersion Modeling
This online technical article provides a sensitivity study of the Gaussian dispersion modeling of continuous, buoyant pollution plumes which illustrates how seemingly minor changes in some of the key variables can result in a propagated overprediction factor ranging from 6 to 80. The same website has four more online technical articles.

Extractions: Air dispersion modeling has been evolving since before the 1930s. Over the last 15-25 years, strict environmental regulations and the availability of personal computers have fueled an immense growth in the use of mathematical models to predict the dispersion of air pollution plumes. Beychok's recently published book, " Fundamentals Of Stack Gas Dispersion ", details the evolution of the widely used Gaussian air dispersion models and their inherent assumptions and constraints. Unfortunately, many users of such models are completely unaware of those assumptions and constraints and mistakenly believe that the precision achievable with computers equates to accuracy. This article discusses how the propagation of seemingly small errors in the Gaussian model parameters can cause very large variations in the model's predictions. In most dispersion models, determining the pollutant concentrations at ground-level receptors beneath an elevated, buoyant plume of dispersing pollutant-containing gas involves two major steps:

http://www.pca.state.mn.us/air/modeling.html

Extractions: PDF documents that require Adobe Acrobat for viewing. Air quality dispersion modeling is a computer simulation that predicts air quality concentrations from various types of emission sources. For pollutants emitted through a stack, it considers the emission rate, stack height, stack diameter, and stack gas temperature and velocity, as well as the effect of nearby buildings and terrain. Other emission sources like vehicle traffic or wind erosion from storage piles are represented as 2-dimensional area sources or 3-dimensional volume sources. Modeling Guidance Meteorological Data Staff Contacts Additional Resources Air quality dispersion models use meteorological data such as temperature, wind direction, and wind speed to calculate concentrations. Five years of National Weather Service meteorological data is typically used for air quality modeling required by the US Environmental Protection Agency (EPA), Federal Land Managers (FLMs), and Minnesota Pollution Control Agency (MPCA). In some cases one year of onsite meteorological data is used. Model results are often compared to benchmark levels such as ambient standards to determine if they meet state and federal requirements. Sometimes results are used to help site ambient monitors or they may be input into health risk assessments or ecological risk assessments.

http://www.wei-air.com/practice/area3.html

Extractions: Air dispersion models are tools to assess impacts from air pollution sources. Why are these tools important? Air permit applicants must show that potential air quality impacts will not exceed specific health thresholds. If used before pollution sources are actually built, air dispersion models can be more advantageous than air monitoring.
