Overview

1. CALPUFF is a Lagrangian puff and elongated-puff (slug) model for pollutant transport & dispersion.
2. CALPUFF is a multi-layer, multi-species non-steady-state puff dispersion model that simulates the effects of time- and space-varying meteorological conditions on pollution transport, transformation and removal.
   
3. CALPUFF can be applied on scales of tens to hundreds of kilometers.
   
4. It includes algorithms for subgrid scale effects (such as terrain impingement), as well as, longer range effects (such as pollutant removal due to wet scavenging and dry deposition, chemical transformation, and visibility effects of particulate matter concentrations).
   
5. It is one of the EPA's Preferred regulatory models
   
6. The  CALPUFF system has many major components, of which we will use four: 
   
• CALWRF to translate WRF netCDF files into the right format for CALMET (get from version 7)
  
• CALMET to extract the meteorology needed to run CALPUFF (get from version 5)
  
• CALPUFF to do the Lagrangian puff dispersion (get from version 5)
• CALPOST to produce postprocessing graphics and statistics (get from version 6).
  
7. And there are many more minor pre- and post-processing systems.

Used For* 

• Atmospheric dispersion modeling both near (10 m) and far (many 100 km) from the pollutant-emissions source, for
  
• non-steady meteorology and complex topography,
• with non-steady point and area sources.
• It can handle passive tracers as well as those that react, fallout, washout, etc.
  
• The model produces output for averaging times of seconds to one year.
