As a result of recent rapid economic
As TAME result of recent rapid economic growth and limited emission controls in Asia, anthropogenic emissions of PM2.5 and O3 precursors like NOx and non-methane VOCs have increased 14, 55, and 29% in China from 2001 to 2006 (Streets et al., 2003, Wild and Akimoto, 2001 and Zhang et al., 2008). Asian pollutants, both natural and anthropogenic, have been observed to impact wide areas of North America, particularly high altitude areas (Jaffe et al., 1999, VanCuren and Cahill, 2002, VanCuren, 2003, Jaffe et al., 2004, VanCuren et al., 2005 and Ambrose et al., 2011). Asian combustion impacts at LAVO have been documented in detail (VanCuren, 2003). Occasional large Asian PM2.5 impacts have been observed due to large dust storms, even driving exceedances of air quality standards (Jaffe et al., 1999 and Husar et al., 2001UNEP, 2010). Asian transport to North America has been shown to be enhanced in the spring when active cyclonic activity and prevailing westerly winds from Asia are ribosomal subunits the strongest (Parrish et al., 2009, Cooper et al., 2010 and Zhang et al., 2008).
