主备份自动气象站气象数据的对比算法研究与应用

Research and Application of Comparison Algorithm of Meteorological Data from Main and Standby Automatic Weather Stations.

以黄石国家气象观测站地面气象数据为例,研究如何将软硬件差异较大的主备双套自动气象站数据放到同一平台进行数据对比分析。通过将绝对差值、标准差值等数据结合的方法进行分析,提升国家级自动气象站的自动探查错与纠错能力,并以地面气象数据中的气温、气压数据为例,将本文数据处理方法代入后进行自动判别试验。结果表明:通过使用本文方法,可以达到自动判别错误数据源的预期效果。

Taking ground meteorological data of Huangshi National Meteorological Station as the samples, we compare and analyze the data of main and standby automatic meteorological stations in the same software. By combining the absolute differences and standard deviation values, we aim to improve the functions of automatic debugging and automatic error correcting of the state-level meteorological stations. Besides, data of temperature and air pressure of ground meteorological data are used for the automatic identification test with the data processing methods proposed by this study. Results show that the expected effects of automatic identification of wrong data source can be achieved.
