Optical Measurement of Asian Dust over Daejeon City in 2016 by Depolarization Lidar in AD-Network

Abstract

Long-term sustained heavy Asian Dust below 3 km was measured in the period of April 22-26 by 2-wavelengths depolarization lidar system. As the comparison results of Daejeon station with other stations in the AD-Net, similarly formed Asian dust had been measured at Nigata, Toyama, Matsue, and Sendai. The route of the dust was examined by HYSPLIT. More than 80 μg / m3 mass concentrations derived from the lidar measurements were compared with Air-Korea PM10 data.
