An Analysis on the Episodes of Large-scale Transport of Natural Airborne Particles and Anthropogenically Affected Particles from Different Sources in the East Asian Continent in 2008

摘要: In 2008, multiple episodes of large-scale transport natural airborne particles and anthropogenically affected from different sources in the East Asian continent were identified National Oceanic Atmospheric Administration (NOAA) satellite RGB-composite images mass concentrations ground level particulate matters. To analyze aerosol size distribution during atmospheric aerosols, both optical depth (AOD; proportional to total loading vertical column) fine weighting (FW; fractional contribution AOD) Moderate resolution Imaging Spectroradiometer (MODIS) products used over region. The six massive observed at Cheongwon, originating sandstorms northern China, Mongolia loess plateau China. PM stood 70% 16% concentration TSP, respectively. However, among TSP increased as high 23% episode which they flowing by way f industrial area east other five that flowed into Korean Peninsula reached 82% 65%, average AOD for particle region was measured 0.42±0.17 compared with (0.36±0.13) episodes. Particularly, regions covering Yellow Sea, Peninsula, sea characterized levels AOD. FW values event aerosols (0.63±0.16) moderately higher than those (0.52±0.13). This observation suggests contribute greatly Asia.
