摘要
针对自动气象站的雨量传感器对应的现场校准方法,就其相关指标和规定的合理性进行探讨,目的在于让现场校准方法更加合理。根据雨量传感器本身的技术性能,结合实际工作经验,以分析误差构成进行理论推导,得出雨量计量性能要求中最大允许误差等不合理的结果,从误差公式中重新确定了雨量的最大允许误差,对雨量现场校准方法指标的确定提出了修改建议。
Aiming at the field calibration method corresponding to rainfall sensor of automatic weather station,this paper discusses the rationality of relevant indexes and regulations,so as to make the field calibration method more reasonable. Based on the technical performance of the rainfall sensor itself,combined with the actual work experience,the theoretical derivation is made by analyzing the composition of the error,and the unreasonable results such as the maximum allowable error in the requirement of rainfall measurement performance are obtained,and the maximum allowable error of rainfall is redefined from the error formula. Some suggestions were put forward for the determination of the index of the field calibration method.
