When conducting an air dispersion modeling analysis, it is very important that the meteorological data quality is as high as possible. AERMET – the meteorological pre-processor for the AERMOD dispersion modeling system – contains internal options which can boost data quality by filling short gaps of missing cloud cover and temperature data.
With each successive update to the AERMOD modeling system published by the U.S. EPA to the Support Center for Regulatory Atmospheric Modeling (SCRAM) website, Lakes Software updates our AERMOD View and AERMET View applications to support the new models. In previous Modeling Tips, we’ve discussed how to choose earlier versions of the AERMOD executable in AERMOD View, but it is also possible to revert to earlier versions of AERMET when using AERMET View.
Lakes Environmental recently released the new AERMOD View Version 11.0 which includes support for the latest U.S. EPA model releases dated 22112 for the AERMOD & AERMET dispersion modeling components. The AERMET 22112 update debuts an entirely new code-base for the regulatory meteorological preprocessor. As illustrated below, the new AERMET has been changed from a three-stage to a two-stage process.
