- Note: The promulgation package which establishes AERMOD as the preferred air dispersion model in the Agency's 'Guideline on Air Quality Models' in place of the ISC3 air dispersion model was signed by the Administrator of the US EPA on October 21. The package was then submitted to the Federal Register office and was published November 9, 2005.
- When you are tasked to put together a dispersion modeling study or related air quality analysis, you need an edge to help you through the process effectively and efficiently. With BEEST, the air quality modeling process has never been easier. BEEST includes all the parts you need for AERMOD, ISCST3 and ISC-Prime air quality modeling.
- Air dispersion modeling provides a visual mathematical simulation of how air pollutants disperse in the ambient atmosphere. Based on emissions source and meteorological data as well as topography information, a dispersion model calculates an estimate of the downwind concentration of pollutants as they travel away from emissions sources.

CALPUFF System: USEPA-Approved Version
This is the version of the modeling system officially approved by the USEPA. As of July 2016, the current versions of the CALMET and CALPUFF codes include the USEPA-approved code changes described in Model Change Bulletin H (MCB-H).
As of October 2011, the USEPA 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 December 14, 2015 (with the exception of CALPOST, which is dated July 24, 2008).
- CALPUFF - Version 5.8.5 - Level 151214
- CALMET - Version 5.8.5 - Level 151214
- CALPOST - Version 6.221 - Level 080724

CALPUFF System: Version 7
Version 7 (TNG) of the CALPUFF modeling system contains many new features. The model updates introduce new source types including roadways, flare modeling and agricultural spraying coupled with AGDISP. The new pre-processor SURFGEN which can process sub-hourly ASOS data and the post-processors CALRANK, CALAVE and CALMAX are also now available.
Features introduced in Version 6 (which is now being archived) are also part of Version 7: chemistry options, such as the ISORROPIA (now updated to v2.2) inorganic gas-particle equilibrium model, aqueous phase chemistry and an anthropogenic secondary organic aerosol (SOA) module based on the CMAQ/MADRID model; options to use sub-hourly time steps for both meteorological and emissions data, nested grid capabilities; an option in CALPOST 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 7.2.1 - Level 150618
- CALMET - Version 6.5.0 - Level 150223
- CALPOST - Version 7.1.0 - Level 141010

BETA Release - A release of the CALPUFF model is available below which includes the new SPRAY source type. Associated post-processors have also been updated. Any comments or questions on this new release are appreciated and can be directed to [email protected]. During this period, CALPUFF Version 7.2.1 remains available as part of our standard Version 7 code distribution.
CALPUFF System: Version 6
Version 6 (v6) of the CALPUFF modeling system has been superseded by Version 7 and has been retained here as an archived version. If Version 6 is required for a specific application it can be downloaded at the link below. Version 6 of the model contains all Model Change Bulletin (MCB) updates only through MCB-G. All features available in Version 6 are now also available in Version 7. Version 7 also includes additional new enhancements.

AERMOD View Introduction AERMOD View is a complete and powerful air dispersion modeling package which seamlessly incorporates the popular U.S. EPA models into one interface: AERMOD, ISCST3, and ISC-PRIME. These models are used extensively to assess pollution concentration and deposition from a wide variety of sources. AERMOD is the next generation air dispersion model designed for short-range (up to 50 kilometers) dispersion of air pollutant emissions from stationary industrial sources. AERMOD is a steady-state plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling, including treatment of both surface and elevated sources, and both simple and complex terrain | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
