HYSPLIT-SV (for Semi-Volatile pollutants)

Fraction of emissions of four dioxin congeners accounted for in different fate pathways anywhere in the modeling domain for a hypothetical 1996 year-long continuous source near the center of the domain (figure 6 from Cohen et al. 2002).

A special version of the HYSPLIT model has been developed to simulate the atmospheric fate and transport of semivolatile pollutants such as PCDD/F (dioxin). Features in HYSPLIT-SV include the following:

  • Deposition accounting for specific point and area receptors
  • Vapor/particle partitioning for semivolatile compounds
  • Atmospheric chemistry: reaction with OH and photolysis
  • Particle size distribution for particle-associated material
  • Particle deposition estimated for each particle size
  • Enhanced treatment of wet and dry deposition
  • Separate output for different deposition pathways
