AERSCREEN Released as the EPA Recommended Screening Model
In August 2010, EPA released a beta version of AERSCREEN with draft user's guide and test cases, taking public comment until September 30, 2010. These comments ranged from "bug" fixes to suggested AERSCREEN enhancements. After incorporating "bug" fixes and user comments, EPA released version 11060 of AERSCREEN on March 11, 2010 with a subsequent update, version 11076, on March 17, 2010. Version 11076 corrected an error found in version 11060. The release package includes AERSCREEN (Fortran source code and executable), a User's Guide, the MAKEMET meteorological data generator, and AERSCREEN test cases. AERSCREEN uses the AERMOD executable, ensuring consistency with the refined model, and also utilizes the BPIPPRM building processor and AERMAP terrain preprocessor as needed to account for building downwash and terrain effects. AERSCREEN can be found on the Support Center for Regulatory Atmospheric Modeling (SCRAM) website.
