Observations of marine aerosol using a scanning micro pulse Lidar in 2015

The observations of marine aerosol over the Yellow Sea near Qingdao were carried out using a ship-borne scanning micro pulse lidar (SMPL) onboard the oceanographic research vessel, XIANGYANGHONG No.8 (XYH-08). The observation campaign including anchor point observation and sailing observation was conducted from September 13th to September 18th, 2015. We acquired observation data of sailing route including aerosol extinction coefficient, the temporal and spatial variation of aerosols and clouds, and the structure of boundary layer and so on. Through the function of 3-dimensional scanning, the SMPL also provided range-height indication (RHI) and plane-position indication (PPI) of observation signals which could well reflect the distribution of marine aerosol in different directions. From the change of aerosol extinction coefficient, we successfully captured a process of sea fog occurrence.
