自动气象站的动态试验及其测量准确度

FIELD TESTS AND MEASUREMENT ACCURACY OF AUTOMATIC WEATHER STATIONS(AWS)

计算了自动气象站动态对比试验结果的相关系数和差值误差区间，从而论证了对比试验的可信度。提出了计算自动气象站测量结果的标准差、合格率、准确度的方法．并用隐含周期分析与自相关模型得出了自动气象站的某些测量结果优于人工观测结果的结论．

Based on the computed correlation coefficients and the error of the differencesbetween the tested values from AWS and the conventional observations,the reliabilityof the comparative tests were demonstrated.A method of calculating the standarddeviation,qualified rate and accuracy of the AWS measurement results were suggested.The hidden periodic analyis and autocorrelation model were used to compute the AWSmeas urement data. The results show clearly that some measurement parameters fromAWS are better than theman-made observations.
