Observing data analysis and correction of JDZ05-1 tipping rain gauge

基于JDZ05-1型翻斗式雨量器与虹吸式雨量计平行对比的大量资料,分析了翻斗式雨量器动态计量误差的感差、器差和余差,通过翻斗计量误差计算公式,提出了用特征曲线进行翻斗计量误差修正的方法,经实测资料验证,可提高翻斗观测数据的精度。

Based on large materials of parallel contrast between JDZ05-1 tipping rain gauge and pure absorb rain gauge it analyses the dynamic calculating error of tipping rain gauge including induction error, rain gauge error and margin error. According to calculating formula of tipping calculating error, it advances a correction method by using characteristic curve to measure tipping calculating error. It can promote accuracy of tipping observing data through practical validation.
