Study on evaluation method of humidity observation data quality based on uncertainty evaluation

为了准确评估现场湿度观测的数据质量,文章通过分析现场观测不同的环境因素对湿度观测数据的影响,基于不确定评估理论建立湿度观测不确定度评估模型,并进行定量分析,评估结果表明自动气象站湿度传感器的不确定度小于2.2%。基于不确定度评定的湿度观测数据质量评估方法,可以有效地评价现场湿度观测数据的准确性,对保证湿度观测资料的可比性和一致性具有重要意义。

In order to accurately evaluate the data quality of on-site humidity observation, this paper analyzes the influence of various environmental factors on the humidity observation data, establishes the humidity observation uncertainty evaluation model based on the uncertainty evaluation theory, and then carries out quantitative analysis.The evaluation results show that the uncertainty of the humidity sensor of the automatic weather station is less than 2.2%.The quality evaluation method of humidity observation data based on uncertainty evaluation can effectively evaluate the accuracy of field humidity observation data, which is of great significance to ensure the comparability and consistency of humidity observation data.
