地温资料的计算机自动审核方法

Method for Auto-Checking Surface Temperature by Computers

地温观测资料的计算机自动审核技术,是地面气象观测资料计算机自动审核中的一个关键性技术难点。综合分析了地温观测资料的特点和地温观测资料的人工审核方法,提出了地温观测资料“相邻差”的标准差分析方法,详细说明了该方法在计算机自动审核中的具体实现步骤和该方法的特点。由于该方法从本质上讲是对人工审核方法的计算模拟,同时由于采用客观计算方法,避免了主观因素,所以审核质量能达到人工审核质量的要求,且比人工审核更全面。该方法在浙江省地面气象资料计算机自动审核软件中进行了试用,实践证明该方法对提高地温观测资料的审核质量具有明显效果。

The auto-checking of surface temperature by means of computers is one of key difficulties in the autochecking of surface meteorological data technically. Based on the analysis of the characteristics of surface temperature observation, a method of standard error （neighboring difference） for automatically checking surface temperature observation data was presented. The steps of this method are introduced in detail. Since the method is the computational simulation of the manual check essentially and the objective computational method is applied, the check quality is the same as the manual check, and even more complete. As a test, the method has been applied in the auto-checking software of surface meteorological data in Zhejiang Province. It has been proven that it shows good effectiveness for improving the quality of surface temperature data check.
