Inter-comparison experiment between two aerosol LIDAR systems at Anmyeon-do

摘要

This study uses the different type LIDAR systems such as Micro Pulse LIDAE (MPL) and Multi Wavelength LIDAR (MWL). The comparison of the LIDAR systems shows the MPL is a good dust measuring system even though it has a single wavelength for observation of vertical aerosol distribution. The vertical aerosol distribution by the MPL was analyzed and compared with the air quality data and meteorological data during the meteorological condition of subsidence inversion. We show how air quality is so bad at the case for continental air inflow and thermal inversion happened simultaneously. The high concentration of air pollutants could happen under the meteorological condition of thermal subsidence inversion. At that time, the BC concentrations appeared high due to aerosol trap under the meteorological condition of thermal subsidence inversion around the surface.
