    摘要:

    气溶胶和风场作为研究海上大气的重要参数,实现高精度测量具有重要意义,为实现海上大气气溶胶和风场的高时空分辨率走航观测,研制了一套船载大气多参数探测激光雷达。主要介绍了船载大气多参数探测激光雷达的结构设计、探测原理、技术指标和反演方法。通过实验标定测试,对系统进行大气分子瑞利散射信号标定及风场观测标定测试,验证了系统的观测特性及准确性。分析了2024年8月搭载“鲁青渔教16”试验船在中国黄海、东海开展的海上低空大气多参数走航观测实验数据,获取了走航观测期间0-10 km的气溶胶光学参数及0-5 km的风场信息。数据结果显示,海上气溶胶浓度变化明显,且存在低空气溶胶层及低空云,海上低空大气风速基本在20 m/s以下;边界层高度分布在1 km附近波动变化;以200 m、500 m、1000 m高度为例,分析了海上不同高度的气溶胶、风速、风向分布存在的差异。实验结果表明,船载大气多参数探测激光雷达可搭载船、浮标等海洋平台,高效实现海洋上空气溶胶与风场的连续精确观测。

    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.
