摘要
利用2017年8月~2018年7月广西区7个国家基准气候站降水现象仪自动观测与人工观测记录,以《降水现象平行观测业务技术规定》为依据,分别从数据准确性、现象发生时段一致性等方面对降水现象的雨记录进行统计分析。结果表明:捕获率较低,漏报率较高,一致性有待提高。建议延长平行观测时间,加强人工质控,进一步提高仪器性能及优化数据处理软件。
Based on the Technical Regulations for Parallel Observation of Precipitation Phenomenon and using the automatic observation and manual observation records of precipitation phenomena at 7 national climatic stations in Guangxi from August 2017 to July 2018, the precipitation phenomena are analyzed from the aspects of data accuracy and the consistency of the occurrence period.The results show that the capture rate is low, the missing rate is high, and the consistency needs to be improved. It is suggested that the parallel observation time be prolonged, artificial quality control be strengthened, instrument performance be further improved and data processing software be optimized.
