CAWS600型自动气象站湿度传感器检定的不确定度分析

自动气象站各要素传感器随着时间的推移和环境的变化，测量误差将会发生漂移。为确保各要素观测数据的准确、可靠并具有可比性，定期开展自动气象站各要素的检定和校准是非常重要的。通过检定将各要素系统误差控制在允许范围内，并对检定结果进行不确定度分析，是考察检定结果可信程度的重要步骤。文章依据自动气象站检定规程要求，并根据检定数据，对自动气象站的湿度传感器检定进行不确定度分析，对自动气象站检定可信度评估具有指导意义。

Uncertainty analysis on humidity sensor of CAWS600 automatic weather station

With the variation of time and environment,errors of each element sensor in automatic weather station will be in drift.Therefore,it is significant to verify and calibrate each sensor regularly in order to ensure accurate,reliable and comparable data.Through the verification,systematic errors of every element should be controlled within the allowable range,and uncertainty analysis on the results is given out.The things mentioned above are important steps to test credible degree of the results.Based on the requirements for verification regulation of automatic weather station,and by means of calibrating data,uncertainty analysis on humidity sensor of CAWS600 automatic weather station is carried out,which plays a guiding role in credibility evaluation of automatic weather station.
