  Feature Sheet


CALPUFF View provides a complete graphical solution for the CALPUFF modeling system: CALPUFF, CALMET, CALPOST, and their related pre- and post-processors. 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
