Download or read book Evaluation of Prognostic Meteorological Data in AERMOD Applications written by and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides an evaluation of prognostic meteorological data in AERMOD. Included in this document are descriptions of the inputs, evaluation of the meteorological data, and evaluation of AERMOD results using observed meteorological data and prognostic meteorological data. This document is an update to the December 2016 document “Evaluation of Prognostic Meteorological data in AERMOD Applications” (EPA-454/R-16-004). This document includes a new Appendix D, which details the differences of model output when using a wind speed threshold of 0.5 m/s and a new 0 m/s threshold as recommended in the updated “Guidance on the Use of the Mesoscale Model Interface Program (MMIF) for AERMOD Applications” (EPA-454/B-18-005). EPA will respond to specific requests for subsets of the data or for specific additional inputs and outputs of the modeling process, depending on the availability of the data. Requests for electronic copies of the air quality modeling data used for this rule should be sent to James Thurman ([email protected]).
