摘要: [1] This study examines the role of aqueous secondary organic aerosol formation in North American Sonoran Desert as a result intense solar radiation, enhanced moisture, and biogenic volatile compounds (BVOCs). The ratio water-soluble carbon (WSOC) to (OC) nearly doubles during monsoon season relative other seasons year. When normalized by mixing height, WSOC enhancement months preceding dry (May–June) exceeds that sulfate factor 10. WSOC:OC are most strongly correlated with moisture parameters, temperature, concentrations O3 BVOCs. No positive relationship was identified between or anthropogenic tracers such CO over full This points at need for further work understand effect BVOCs altering properties understudied desert regions.
