摘　　要：文章选取鄱阳国家基本气象站2018年1~3月DGS5型降水现象仪观测资料进行统计分析。采用人工观测天气现象资料作为参照标准,对降水现象仪进行准确性分析。结果表明:降水现象仪观测数据完整性满足目前的业务需求;仪器对降水(阵雨)天气现象观测捕获率较高,对于微量降水捕获率较低。The observation data of DGS5 precipitation instrument in Poyang national basic automatic station from January to March in 2018 were selected for statistical analysis.The weather observation data are used as the reference standard to analyze the accuracy of the precipitation instrument.The results show that the data integrity of precipitation instrument meets the current operation needs.The instrument has a high capture rate for observation of precipitation(shower)weather phenomena,but having a low capture rate for trace precipitation.
