3SAQS 2008b Modeling Platform

Abstract

The 3SAQS project performed photochemical grid modeling (PGM) for the year 2008 using the Comprehensive Air Quality Model with Extensions (CAMx) version 5.41. The 3SAQS 2008 Modeling Protocol details the CAMx configuration and justification for why it was chosen for the 3SAQS. Version B of the 3SAQS base 2008 modeling platform (3SAQS_Base08b) includes CAMx results for 36-km, 12-km, and 4-km modeling domains. The 3SAQS 2011a modeling platform is evolving to include a future projection year (2020), diagnostic sensitivity case studies, and a Community Multiscale Air Quality (CMAQ) model simulation. The set-up and configuration of the 3SAQS 2011 platform was derived from the 3SAQS 2008 version B (3SAQS_CAMx_Base08b) modeling platform, but differs significantly in the input data and models used in the simulation.
