双翻斗和称重雨量传感器的数据对比分析

Comparative analysis on the data between double tipping bucket and weighing rain sensor

文章利用2015年4~8月,根据台站的两台SL3-1双翻斗雨量传感器和一台DSC2称重雨量传感器采集的数据,对两种传感器的测量情况作了对比分析。因仪器结构原因,翻斗雨量传感器易发生堵塞而造成降水异常;称重雨量传感器易发生不稳定跳动而造成降水异常。

The measuring results of two kinds of sensors were analyzed by using the data which were collected by two SL3-1 double tipping bucket rain sensors and one DSC2 weighing rain sensor from April to August in 2015. The double tipping bucket rain sensor can be easily blocked because of the instrument structure, so that the precipitation result is abnormal. However, the weighing rain sensor usually has unstable oscillation that caused abnormal precipitation.
