# The CALPUFF Modeling System
The CALPUFF modeling system has 3 main components, each with the capability of being applied using a graphical user interface (GUI). In addition to t hese components, there are numerous other geophysical and meteorological processors that may be used to prepare or examine data used in the system.

# CALPUFF System: EPA-Approved Version
This is the version of the modeling system o fficially approved by the U.S. EPA. The current versions of the codes include changes docum ented in Model Change Bulletins (MCB) through MCB

- D , which reflect updates from the previ ous (July 2004) EPA-approved versions. Note that the EPA version of the modeling system does not include MCB

- E or MCB

- F which have been implemented in the current Ve rsion 6 of the model. Most of the MCB

- E changes

- E and provided to EPA on June 27, 2008. MCB

- F was provided to EPA for review on February 16, 2011. Re view material related to MCB

- G is currently being prepared for EPA. Once EPA reviews and approves the changes , the EPA-approved version of the model will be updated. The main system programs in this area are dated June 2007:

• CALPUFF - Version 5.8 - Level 070623

• CALMET - Version 5.8 - Level 070623

• CALPOST - Version 5.6394 - Level 070622



# CALPUFF System: Version 6.42
Version 6 (v6) of the CALPUF F modeling system contains m any 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. Vers ion 6 also includes options to use subhourly time steps for both meteorological and em issions data, nested gr id capabilities, many GUI enhancements and new GUI modules. Version 6 of the model cont ains all Model Change Bulletin (MCB) updates through MCB

- G . The CALPOST v6 program contains the recommended FLAG (2010) techniques on visi bility/regional haze assessments. In addition, CALPOST v6 contains an option to compute dai ly peak one-hour concentration val ues consistent with the new U.S. 1-hour SO 2 and NO 2 standards.
The main system programs are:

• CALPUFF - Version 6.42 - Level 110325

• CALMET - Version 6.334 - Level 110421

• CALPOST - Version 6.292 - Level 110406
