摘要
WUSH-RG型山洪雨量站观测要素为降水量,其传感器为上海气象仪器厂生产的SL-3型雨量传感器。为了保证观测精度,中国气象局要求定期对传感器进行现场核查,现场核查项目主要包括外观检查和示值误差核查,经外观检查各项指标均符合要求且示值误差不超出±0.4 mm的传感器为合格。使用合格的传感器是保证观测数据准确性的前提条件。
The WUSH-RG type flash flood rainfall station observation element is precipitation,and the sensor is SL-3 type rainfall sensor produced by Shanghai Meteorological Instrument Factory.In order to ensure the accuracy of observation, China Meteorological Bureau demands that the sensor is required to carry out on-site verification,on-site verification project mainly includes the appearance inspection and the error of verification value, the examination of the indicators are in line with the requirements and the error of the value does not exceed 0.4mm.The use of qualified sensor is the precondition to ensure the accuracy of the observation data.
