| Using
HYSPLIT as a Puff Dispersion Model
Modeling Point Sources with HYSPLIT The HYSPLIT
model has been used extensively by the Air Division Planning
Section as a forward dispersion model to evaluate large point
sources of air pollution which are hundreds of kilometers away
from Vermont as well as point sources located within or near
to the state's boundaries. The Division uses archived wind fields
obtained from the
National Oceanographic & Atmospheric Administration (NOAA)
to model single point
sources and multiple
source groups. These studies are being done in order to
help us quantify potential contributions to aerosol concentrations,
acidic deposition, and regional haze in Vermont from sources
outside the state. Model results are only preliminary at this
time and the modeling approach is still in a testing phase.
