计算自动气象站动态准确度的新方法

A New Method of Calculating Dynamic Accuracy of Automatic Meteorological Stations

介绍了一种计算自动气象站动态准确度的新方法，通过对同在杭州的两台自动站和人工站对比数据的计算，结果表明，用这种方法计算出来的人工站、自动站的各要素的标准差是适用的、客观的。人工站资料的标准差的计算结果和以前的假定值是相近的，自动站的计算结果符合ＣＩＭＯ（世界气象组织所属仪器和观测方法委员会）对自动站测量准确度的要求。

A new method of calculating the dynamic accuracy of automatic meteorological station (AMS) is introduced. The computational results of the data observed with two AMS and one meteorological station in Hangzhou show that the standard deviation of the AMS and the meteoro-logical station are appropriate and objective. The computational results of the meteorological station data are approximatly the same as previously assumed values. The standard deviations of AMS are much smaller than the value required by CIMO (Committee of instrument and method of observation of WMO),and satisfy the accuracy requirment of AMS by CIMO.
