摘要
文章利用2017年8月~2018年1月东胜站DSG5降水现象仪自动观测数据及人工观测记录,对降水现象仪进行评估和分析。结果表明:降水现象仪捕获率较高,误报率为5.7%,主要表现为毛毛雨的判别与人工观测记录不一致,降水符合率为71%。建议配合摄像头等辅助设备,提高人工观测质量,保证参考标准值(人工观测记录)的准确度,对典型降水过程进行加密观测或延长平行观测时间后继续进行评估分析。
Using the observation data of DSG5precipitation instrument and manual observation records from August2017to January2018at Dongsheng station,the DSG5phenomenon instrument is evaluated and analyzed.The results show that the capture rate of precipitation instrument is higher and the false alarm rate is5.7%.The main difference is that the records of precipitation phenomena are not consistent with the records of manual observation for the drizzle.And the precipitation coincidence rate is71%.It is recommended to cooperate with auxiliary equipment such as cameras to improve the quality of manual observation,guaranteeing the accuracy of reference standard values(manual observation records).After intensive observations on typical precipitation process or extended parallel observation time,the evaluation and analysis will be continued.
