DSC1型称重与SL3-1翻斗雨量传感器实际应用中观测液态降水的差异

Differences of liquid precipitation observed in practical application of DSC1 weighing and SL3-1 tipping bucket rainfall sensor

文章从DSC1型称重和SL3-1型翻斗雨量传感器的工作原理出发,选取2015年和2016年4~10月章丘大监站同时段的称重与翻斗雨量传感器观测的液态降水量,进行总量、过程降水量差值及捕获有效降水量的时间进行比较,分析两种降水设备的差异以及造成降水测量误差的原因主要是受降水强度和持续时间的影响,降水越弱,持续时间越长,两者测量的差值越大。

Based on the working principle of DSC1 weighing and SL3-1 tipping bucket rainfall sensor,the total amount of liquid precipitation,precipitation difference and the time to capture effective precipitation were compared and analyzed at Zhangqiu big monitoring station from April to October in2015 and 2016.The great differences between two devices in measurement of liquid precipitation are mainly caused by precipitation intensity and duration.That is to say,the weaker the precipitation is,the longer the precipitation lasts and the greater the measurement difference is.
