Multiscale Modeling of Ozone Formation and Chemical Regimes in Arizona during the North American Monsoon
Ground-level ozone (O3) remains a persistent air-quality challenge in the Southwest U.S. desert, including Arizona, despite nationwide emission reductions. Here, we apply the variable-resolution global chemistry–climate model MUSICAv0 to investigate O3 formation, transport, and chemical regime variability across Phoe...
