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,36-km and 4-km12-km modeling domains. The 3SAQS
