Abstract:
通过EWPG1500型称重式雨雪量计与同一观测场内人工雨量计、数字自记雨量计的观测数据对比,来分析研究其运行性能。重点以人工雨量计观测数据作为真实值建立相关关系分析数据相关性、以称重雨量计与人工雨量计观测数据的误差值是否满足许可误差来分析数据合格率、以人工模拟降雨进行不同雨强的注水实验来分析仪器精度等方面进行比测分析,结果表明,EWPG1500型称重式雨雪量计与人工雨量计、数字自记雨量计仪器观测数据的相关性较好,但相较人工日雨量观测合格率略低。
In this paper, the operation performance of EWPG1500 automatic weighing rain gauge was analyzed by comparing its observation dates with those of manual observation and digital rain gauge. Research priorities included correlation and qualified rate analysis of EWPG1500 automatic weighing rain gauge by regarding manual observation dates as true value. The instrument precision was analyzed by water injection test, which simulated different rainfall intensity. The results show that the EWPG1500 auto-matic weighing rain gauge had a good correlation with the observation data of other instruments, but the qualified rate was slightly lower than that of artificial daily rainfall observation.
