Lidar network observations of tropospheric aerosols in East Asia

[ABSTRACT]Observations of tropospheric aerosols using a ground-based network of two-wavelength (532nm, 1064nm) polarization (532nm) lidars (SKYNET-lidar < NIES Lidar Network < AD-Net < GALION) are reported. Currently, the lidars are continuously operated at 18 locations in East Asia, including 3 stations in Mongolia, Seoul, Korea, and Phimai, Tailand. The data from the lidars in the network are transferred to the National Institute for Environmental Studies (NIES) in real time and processed to derive the attenuated backscattering coefficients at the two wavelengths and the volume depolarization ratio. The extinction coefficient estimates for non-spherical aerosols (dust) and spherical aerosols are also derived automatically with the real-time data processing system. The data from the network are used in various studies on atmospheric environment and climate change. In this paper, we report on the lidar instrument and the network, the data analysis methods for estimating aerosol components, and the results of recent studies on Asian dust, air pollution aerosols, and forest fire smokes. The role of the lidar network in the GAW Aerosol Observation Lidar Network (GALION) and the role of GALION in climate change studies will be also discussed.
