All three modeling systems are supported by the interface:

  • USEPA Approved Version 5.8
  • Version 6
  • Version 7

CALPUFF View includes powerful and independent QA tools, stunning report-ready results, and a wide range of visualization options.

CALPUFF is a sophisticated model and is used in many modeling scenarios including:

  • Toxic pollutant deposition
  • Visibility assessments
  • Complex terrain
  • Secondary pollutant formation
  • Long range and overwater transport
  • Building downwash
  • Costal interaction effects
  • Dry deposition
  • Fumigation conditions
  • Chemical transformation
  • Sub-hourly time steps
