Key changes since Beta release (PDF) (1 pg, 127 KB, 03-11-2011)Ĭlarification on AERSCREEN as Recommended Screening Model (PDF) (3 pp, 268 KB, 04-11-2011)ĬOMPLEX1 is a multiple point source screening technique with terrain adjustment that incorporates the plume impaction algorithm of the VALLEY model. These programs can be downloaded from the AERMOD Modeling System section.ĪERSCREEN code and executables (v21112) (ZIP) (926 KB, 04-22-2021) - 64-bit Operating SystemsĪERSCREEN code and executables (v21112) (ZIP) (847 KB, 04-22-2021) - 32-bit Operating Systems Please note that before using AERSCREEN, users must have the latest AERMOD executable (09292 or later) as well as the AERMAP terrain preprocessor and BPIPPRM executables. The MAKEMET program interfaces with AERSCREEN to generate a site-specific matrix of screening meteorological conditions based on user inputs for input into AERMOD. AERSCREEN is intended to produce concentration estimates that are equal to or greater than the estimates produced by AERMOD with a fully developed set of meteorological and terrain data, but the degree of conservatism will vary depending on the application.ĪERSCREEN (Version 16216) code including the latest MAKEMET code (Version 16216) is provided below along with documentation and test cases.
The model will produce estimates of "worst-case" 1-hour concentrations for a single source, without the need for hourly meteorological data, and also includes conversion factors to estimate "worst-case" 3-hour, 8-hour, 24-hour, and annual concentrations. Screening Models and DocumentationĪERSCREEN is the recommended screening model based on AERMOD. The models in this section include AERSCREEN, CA元QHC, COMPLEX1, CTSCREEN, RTDM3.2, SCREEN3, TSCREEN, VALLEY, and VISCREEN. The models listed here are screening models that are usually applied before the refined air quality model to determine if refined modeling is needed.
