WRAP/WAQS 2014v1 Shake-Out Study


The objectives of the WRAP/WAQS 2014 Platform Development and Shake-Out Study (“Shake-Out Study”) is to develop regional photochemical grid model (PGM) modeling platforms for the western U.S. and 2014 calendar year using existing information. The Shake-Out Study 2014 PGM modeling platforms will be used for regional haze State Implementation Plans (SIPs) and potentially other air quality issues in the western states. The first two phases of the Shake-Out Study were performed during the first four months of 2019 and culminated in version 1 (2014v1) of the annual CMAQ and CAMx PGM 2014 base case simulations, model performance evaluation and documentation as described below.
