    Abstract:

    Aerosol and wind field are important parameters for studying the marine atmosphere, and it is of great significance to achieve high-precision measurements. In order to realize high-temporal and spatial resolution airborne observation of atmospheric aerosols and wind fields at sea, the ship-borne atmospheric multi-parameter detection lidar has been developed. The structural design, detection principle, technical indicators and retrieval method of ship-borne atmospheric multi-parameter detection lidar are introduced. Through experimental calibration tests, the system was calibrated for atmospheric molecular Rayleigh tests and wind field observation calibration tests, which verified the observation characteristics and accuracy of the system. The experimental data of low-altitude atmospheric multi-parameter walking observation at sea carried out in the Yellow Sea and East China Sea of China on board the "Luqing Yujiao 16" test vessel in August 2024 were analyzed, and aerosol optical parameters of 0-10 km and wind field information of 0-5 km during the walking observation period were obtained. The data results show that the aerosol concentration at sea changes significantly, and there are low-level aerosol layers and low-level clouds. The atmospheric wind speed at low-level sea is basically below 20 m/s; the boundary layer height distribution fluctuates around 1 km; taking altitudes of 200 m, 500 m and 1000 m as examples, the differences in aerosol, wind speed and wind direction distribution at different altitudes on the sea are analyzed. Experimental results show that atmospheric multi-parameter detection lidar can be equipped with ocean platforms such as ships and buoys to efficiently achieve continuous and accurate observations of aerosol and wind fields over the ocean.
