To examine the optical properties of aerosols and Asian dust, continuous monitoring has been performed at more than 20 lidar stations in the Asian Dust Network (AD-Net). Dual wavelengths depolarization lidar has been applied since 2010 at the Daejeon station (127.34E, 36.33N) in South Korea. This lidar system consists mainly of high power Nd:Yag laser, 300 mm telescope, and optical spectrometer with vertical and parallel depolarization channels at the two wavelengths of 532 nm and 1064 nm. For the analysis of aerosols and Asian dust, backscatter coefficients and depolarization ratios were retrieved with the assumption of the mixing condition of aerosols and molecules. The ratio of backscattering coefficient and depolarization ratio between the 532 nm and 1064 nm were then achieved. To know the spatial and temporal variation of Asian Dust, the results of the depolarization ratios and the backscatter coefficients measured at Daejeon station were analyzed and compared with the results measured from other lidar stations in the AD-Net.
