Convective dust events are common in the greater Phoenix area over summer. These short-duration degrade air quality and pose a potential health threat to millions. In this study, 93 convective that occurred July August 2015 2021 were examined determine their impact on quality. Seven PM10 stations used evaluate changes concentrations different time intervals (10-min, hourly, daily). Out of these events, only 15.1% had daily average above EPA threshold, however, 12.8 28 times lower compared hourly 10-min (respectively) at peak dust. 10-minute 2.2 ± 0.8 higher than concentrations. The findings study demonstrated traditional methods use or averages underestimate atmospheric during short therefore estimated exposure. There is need consider shorter capture PM accurately highlight importance real-time monitoring accurate characterization assess impacts human health.
