INTEX−B Intercontinental Chemical Transport Experiment Phase B NASA driven campaign April-May 2006

Sulfate enhancement in free troposphere Organic enhancement in boundary layer Sulfate mass scaled by 1.4 to compensate for size restrictions Trans−Pacific sulfate observed at Whistler? Altitude [km] Pressure [hPa] Aerosol Concentration [µg/m 3 ] H 2 O Concentration [g H 2 O/kg] SO 4 = Org NH 3

Sulfate contributes to East Asian AOD Model (GEOS-Chem) MODIS MISR MODIS MISR All Dust Model SO 4 = Model held at 2000 anthropogenic emissions

Fall AOD trend reflects SO x emissions 6.2 – 9.6% emission growth per year MODIS MISR All Dust Model SO 4 = Model held at 2000 anthropogenic emissions

Asian sulfate dominates INTEX−B sulfate Filter Pack 25% higher than unscaled Mist Chamber C130 and Cessna measurements scaled by 1.4 Aircraft Full Emissions No East Asia Model No Anthro.

Significant growth to East Asian contribution x increase in simulated East Asian contribution since 1985 Aircraft Full Emissions No East Asia Model No Anthro.

Long − range transport affects NA sulfate burden April-May 2006 Persistent East Asian contribution at 4 km Near Vancouver: –25-30% of surface sulfate of east Asian origin –40% of sulfate burden (1-5 km) of east Asian origin Altitude [km] SO 4 = at 2.0 km Altitude [km] % Asian SO 4 = SO 4 = [ µ g/m 3 ]

Long−range transport degrades surface air quality Mean surface conditions well correlated with simulated East Asian influence during April-May 2006 Mean increase of 0.38 µg/m 3 per +10% Asian influence % Asian (simulated) Measured SO 4 = [ µ g/m 3 ]

Conclusions % annual mean increase in anthropogenic East Asian SOx emissions since x increase in the relative contribution of East Asian sulfate since 1985 Anthropogenic East Asian sulfate degrades NA surface air quality
