I have been using your products for many years and I am definitely a fan! Air Dispersion Modeling. Release Notes. AERMOD fully incorporates the PRIME building downwash algorithms, advanced depositional parameters, local terrain and urban heat island effects, and advanced meteorological turbulence calculations.
AERMOD is used extensively to assess pollution concentration and deposition from a wide variety of sources in locations all over the world. Why Pay for Add-ons that Should be Standard? We have an extensive list of standard features included with AERMOD View, a list that no other software package comes close to having or only as add-ons that cost you more.
OCD - A straight line Gaussian model developed to determine the impact of offshore emissions from point, area or line sources on the air quality of coastal regions. Through AERMIC, a modeling system, AERMOD, was introduced that incorporated air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of both surface and elevated sources, and both simple and complex terrain. This tool calculates and outputs the rolling cumulative all sources 3-month average concentration at each modeled receptor with source group contributions and the maximum cumulative all sources rolling 3-month average concentration by receptor.
The model code and supporting documents are not static but evolve to accommodate the best available science. Please check this website often for updates to model code and associated documents. The model contains, in its entirety, the technology of CTDM for stable and neutral conditions. The EPA can evaluate community-supplied white papers, and if appropriate, incorporate to the Model Development and Update Plan and distribute to the wider stakeholder community.
Chris epa. Skip to main content. Contact Us. Background The Guideline on Air Quality Models published as Appendix W to 40 CFR Part 51 is used by the EPA, other federal, state, territorial, and local air quality agencies, and industry to prepare and review new source permits, source permit modifications, SIP submittals and revisions, conformity, and other air quality assessments required under EPA regulation.
The emphasis is that there is a clearly demonstrable deficiency in the model related to specific features or formulations of the model e. Summary of current literature or research — In general, the modeling issues addressed in the model development plan white papers have some sort of path forward, i.
