Using CALPUFF Modeling System for Source Region Identification


CALPUFF Modeling Domain

Air quality modeling can be done on many different scales. The CALPUFF system is particularly designed for modeling source emission impacts at receptors located at distances of several hundred kilometers. The Planning Section uses CALPUFF on the domain shown at the right to better understand the impacts of large coal-burning power generation units located as much as 1000 kilometers distant from Vermont. The modeling requires obtaining both very good emissions data for the sources of interest and also the development of very detailed wind fields from real measurement data at many meteorological stations across the domain. Good hourly emissions data is available for recent years from the EPA Acid Rain Reporting program. The meteorological data required by the modeling system is chosen to represent surface and upper air conditions as accurately as possible.
