CALPUFF System: USEPA-Approved Version

 

This is the version of the modeling system officially approved by the USEPA. As of December 2013, the current versions of the codes include USEPA-approved portions of code changes described in Model Change Bulletin E (MCB-E), MCB-F and MCB-G. USEPA has approved only those portions of the Model Change Bulletins that are recognized as bug fixes. All other code changes (enhancements and new features) are not included at this time. A memo describing bug fixes versus enhancements is available on SCRAM.

As of October 2011, the USEPA has approved an update in CALPOST from V5.6394 (level 070622) to V6.221 (level 080724). This version includes "Method 8" (MVISBK = 8, M8_MODE = 5, MVISCHECK = 1), which utilizes the revised IMPROVE equation per the Federal Land Managers' Air Quality Related Values Work Group (FLAG) revised October 2010 report. 

The main system programs in this area are dated July 31, 2013 (with the exception of CALPOST, which is dated July 2008).

  • CALPUFF - Version 5.8.4 - Level 130731
  • CALMET - Version 5.8.4 - Level 130731
  • CALPOST - Version 6.221 - Level 082724

CALPUFF System: Version 6.42

 

Version 6 (v6) of the CALPUFF modeling system contains many new features. The model updates include new chemistry options, such as the ISORROPIA v2.1 inorganic gas-particle equilibrium model, aqueous phase chemistry and an anthropogenic secondary organic aerosol (SOA) module based on the CMAQ/MADRID model. Version 6 also includes options to use sub-hourly time steps for both meteorological and emissions data, nested grid capabilities, many GUI enhancements and new GUI modules. Version 6 of the model contains all Model Change Bulletin (MCB) updates through MCB-G. The CALPOST v6 program contains the recommended FLAG (2010) techniques on visibility/regional haze assessments. In addition, CALPOST v6 contains an option to compute daily peak one-hour concentration values consistent with the new U.S. 1-hour SO2 and NO2 standards. 

The main system programs are:

  • CALPUFF - Version 6.42   - Level 110325 
  • CALMET   - Version 6.334 - Level 110421 
  • CALPOST - Version 6.292 - Level 110406
