Source Apportionment of Visibility in Hong Kong

Abstract

A discussion covers visibility across the Victoria Harbor in Hong Kong; post study in Hong Kong, wherein the top three contributors are ammonium sulfate, elemental carbon, and organic carbon; seven pollution sources based on the characteristic explained variance values, i.e., vehicle exhaust, residual oil combustion, fresh sea salt, sea salt, secondary sulfate, secondary nitrate, and biomass burning; locations of meteorological observation stations and sampling site; data description and preprocessing; comparison of PM2.5 source contributions in 00/01 and 04/05 campaigns; mass extraction efficiencies derived from MLR and PMF; and comparison of the source contribution to Bext in 00/01 and 04/05 campaign. This is an abstract of a paper presented at the 103rd Air and Waste Management Association Annual Conference and Exhibition (Calgary, Alberta, Canada 6/22-25/2010)
