The AERMET meteorological data pre-processor contains many different features designed to aid users in performing quality control tasks as data are processed. This includes the ability to audit specific variables, modify valid data ranges, and more.
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.
AERMET – the meteorological pre-processor for the AERMOD modeling system – allows users to input their own custom meteorological data via its Onsite Pathway. This produces a highly representative dataset when using observations recorded at the site that will be modeled in AERMOD.
Most users are aware of Lakes Environmental Software’s Import from Excel utility which reads hourly meteorological data from an Excel spreadsheet and generates a text-based data file in SAMSON format. The generated file can be used in a variety of air modeling applications.
