摘要
为掌握超声波测风仪传感器在特殊气候条件下的运行稳定性和数据对比性,文章利用威宁国家基准站2020-09-01—2020-09-30超声波测风仪和机械风测风仪外场试验的逐分钟数据,分析了4套超声波测风仪的数据完整性和一致性。文章详细介绍了数据完整性的缺测率和数据一致性的评估计算方法;同时对观测资料的计算结果进行了完整性、系统误差、标准偏差分析以及风向频率对比分析和讨论。
In order to grasp the operation stability and data comparison of ultrasonic wind meter sensors under special climatic conditions,this paper analyzes the data integrity and consistency of four sets of ultrasonic wind meters by using the minute-by-minute data of field tests of ultrasonic wind meter and mechanical wind meter at Weining national reference station from September 1,2020 to September 30,2020.This paper introduces the evaluation and calculation method of missing rate and data consistency of data integrity in detail.At the same time,the calculation results of the observation data are analyzed and discussed,including integrity,system error,accuracy deviation and wind direction frequency comparison.
