Predicting the Movement of Hazardous Airborne Material
Predicting the Movement of Hazardous Airborne Material
Jonathan D. W. Kahl
Atmospheric scientists have long studied the processes that control
the transport and dispersion of airborne material. These processes
include the identification of sources, chemical transformations,
processing by clouds, atmospheric diffusion and deposition. Long-range
dispersion models are used to study a variety of air pollution problems
including acid rain, haze and visibility, and ozone. These models are
also used to study the effects of unplanned releases, such as
chemical spills, nuclear accidents and potential terrorist strikes.
This presentation will outline the major characteristics of
atmospheric dispersion models, and will demonstrate a modeling system
used as part of the United State's emergency response system.
