OVERVIEW

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

About CALPUFF

CALPUFF is a multi-layer, multi-species non-steady-state puff dispersion model which simulates the effects of time-and space-varying meteorological conditions on pollution transport, transformation, and removal. The CALPUFF modeling system includes:
  • CALMET – Diagnostic three-dimensional meteorological model
  • CALPUFF – The puff dispersion model
  • CALPOST – Post-processor for calculating time-averaged concentrations, deposition fluxes, and visibility impacts

Why CALPUFF

  • CALPUFF can be applied to a wide variety of scenarios including far-field impacts (those beyond 50km from releases) which cannot be modeled with traditional plume models (e.g., AERMOD).
  • Its three-dimensionally varying meteorological field makes it useful for regions with very complex terrain or non-steady-state conditions.
  • CALPUFF View’s wide range of features make it easy to execute the entire suite of pre- and post-processors for a modeling analysis
