WAQS 2011b Modeling Platform

Abstract

The 3SAQS project performed photochemical grid modeling (PGM) for the year 2011 using the Comprehensive Air Quality Model with Extensions (CAMx) version 6.20 and the Community Multiscale Air Quality (CMAQ) model version 5.0.2. The 3SAQS 2011 Modeling Protocol details the CAMx and CMAQ configurations and justification for why they were chosen for the WAQS. Version B of the WAQS base 2011 modeling platform (WAQS_Base11b) includes air quality modeling results for 36-km, 12-km, and 4-km modeling domains. The WAQS 2011b modeling platform includes a future projection year (2025) and CAMx source apportionment studies. The set-up and configuration of the WAQS 2011b platform was derived from the 3SAQS 2011 version A (3SAQS_CAMx_Base11a) modeling platform, but differs significantly in the input data used in the simulation.
