DOIAbstract
This study examines the extraordinarily long-lasting episode of high concentrations of particulate matter with diameter <10 mu m (PM10) in Seoul, Korea over the period October 16-20, 2008. The concentration of PM10 increased up to 197.2 mu g m(-3) and continually stayed above the daily environmental control standard value (100 mu g m(-3)) for the period. Satellite retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS), Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) showed pronounced transport of aerosols from China to the Korean peninsula prior to the high-PM10 episode. The updraft of air pollutants from the source region in China, transport by westerlies, and subsequent descent to Seoul metr...
