| Abstract | A transport event in April 2001 brought substantial quantities of mineral dust from Asian deserts to the U.S. atmospheric boundary layer (ABL). The dust was seen in large amounts throughout the ABL in the U.S., with almost no reduction in concentrations. It was estimated that the amount of Asian dust in the continental U.S. ABL in mid-April 2001 was 1.1 E5 metric tons, a value comparable to the daily emission flux of all U.S. sources of particulate matter (PM) less then 10 urn diameter (PM10). In some regions, the Asian dust, combined with local pollution, elevated urban PM to levels associated with adverse health effects. The April 2001 event appears to be the largest Asian dust event ever observed in the U.S., and its effects provide evidence that air pollution issues must be viewed in a global context. In late April 1998, satellites, ground-based lidar, and surface sites observed a large cloud of dust as it moved from Asia to North America. At the time, this was believed to be the largest Asian dust event ever seen in North America [Husar et aL, 2001] .An even larger Asian dust cloud was observed in April 2001. The concurrent ACE-Asia experiment provided a large number of observations as this air mass left the Asian continent [Huebert et aL, 2003] .The arrival of this air mass over North America has been documented using surface and satellitebased, remotely sensed data [Thulasiraman et aL, 2002], aircraft observations [Price et aL, 2003], and with a transport model [Gong et al., 2003] .This article describes the influence this dust event had on the U.S. ABL. |
