Assessment System for Population Exposure Nationwide
Entry ID: EPA_ASPEN
[ Get Service ]
[ Update this Record ]


Summary
Abstract: The Assessment System for Population Exposure Nationwide (ASPEN) consists of a
dispersion and a mapping module. The dispersion module is a Gaussian
formulation based on ISCST3 for estimating ambient annual average
concentrations at a set of fixed receptors within the vicinity of the emission
source. The mapping module produces a concentration at each census tract. Input
data needed are emissions data, meteorological data and census tract data. The
Emissions Modeling System for Hazardous Pollutants (EMS-HAP) is needed to
process the emission inputs into the ASPEN model or the ISC3 model. The ASPEN
model was used in estimating annual ambient concentrations for air toxics
pollutant in the National Air Toxics Assessment (NATA) Study.
