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 these 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 officially approved by the U.S. EPA. The current versions of the codes include changes documented in Model Change Bulletins (MCB) through MCB-D, which reflect updates from the previous (July 2004) EPA-approved versions.

Note that the EPA version of the modeling system does not include MCB-E which has been implemented in the current Version 6 of the model. Most of the MCB-E changes were sent to EPA on February 14, 2008 for review and approval. Some additional changes were added to MCB-E and provided to EPA on June 27, 2008. 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
