摘　　要：文章主要研究了激光雨滴谱仪探测原理、雨滴谱形成机制及降水现象识别判断方法,通过对2018年江苏省70个气象台站雨滴谱仪识别判断的降水类型数据与人工观测数据进行统计比对分析,从准确性(捕获率、漏报率、错报率、空报率和起止时间绝对误差)和一致性(起止时间差15 min或以内、15 min以上)等方面进行数据可用性评估。This paper mainly studies the detection principle of laser raindrop spectrometer,the raindrop spectrum formation mechanism and rainfall phenomenon recognition and judgment methods.Through the statistical comparison and analysis of precipitation type data identified and judged by raindrop spectrometers at 70 meteorological stations in Jiangsu Province in 2018 and manual observation data,the data availability was evaluated from the aspects of accuracy(capture rate,missed report rate,false report rate,false report rate and absolute error of start and end time)and consistency(the difference of starting and ending time,15 min or less,above 15 min).
