摘要
对贺州站2004～2005年自动站与人工站平行观测的气温资料进行资料差异性分析,对气温月、日平均值及其平均差值进行了显著性检验,结果表明自动站气温和人工站气温数据差异性不显著,资料的连续性很好,但仍存在一定的系统误差。如能采用适当的方法进行订正,将极大地提高资料的可用性。
Basing the difference analysis between the automatic weather station（AWS）data and the manual station data in Hezhou City from 2004 to 2005,the monthly mean temperature,daily mean temperature and their mean difference were significant tested.The results show that temperature data of AWS and artificial stations have no significant differences,and the continuity of data is good except for a certain systematic errors.
