AIR DISPERSION MODEL

CALPUFF View

Puff Air Dispersion Model
CALPUFF View provides a complete graphical solution for the CALPUFF modeling system: CALPUFF, CALMET, CALPOST, and their related pre- and post-processors. Supports USEPA Approved Version 5.8, Version 6, and Version 7.

CALPUFF Software Interface

Sophisticated Modeling Scenarios

CALPUFF is recommended for a wide range of complex environments where steady-state models fall short.

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

The Modeling System

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.

CALMET – Diagnostic three-dimensional meteorological model
CALPUFF – The puff dispersion model
CALPOST – Post-processor for calculating time-averaged concentrations, deposition fluxes, and visibility impacts

Superior Performance

  • Far-field impacts (beyond 50km) which cannot be modeled with traditional plume models like AERMOD.

  • Three-dimensionally varying meteorological field makes it useful for regions with very complex terrain.

  • CALPUFF View’s features make it easy to execute the entire suite of pre- and post-processors.
