关于翻斗式雨量传感器误差检定的思考

Thinking on Examination of Errors for Tipping Bucket type Rainfall Gauges

翻斗式雨量传感器是一种水文、气象观测仪器,它对自然界降雨的测量误差将直接影响雨量数据收集的精度。由降雨强度不确定性而造成的误差是动态过程引起的,是进行误差检定的主要内容。通过分析目前安装在野外使用的翻斗式雨量传感器检定方法的不便,提出了适用野外模拟大、中、小雨强检定的新方法。

A Tipping bucket type Rainfall Gauge is used in hydrological and meteorological observation. The precision of rainfall data collected is influenced by errors in measurement which is mainly caused by the dynamic process of unstable rainfall. After analyzing the inconvenience of instrument calibration in field at present stage, the author comes forward a new calibration method by simulating high, medium, and low rain intensity.
