新型站与备份站自动气象站数据差异性分析

利用2014年本溪国家基本气象站有效数据资料,将新型和备份2套自动气象站逐时气温、气压等要素的观测值进行了对比分析和探讨,并根据相关标准对本溪气象数据资料进行评估。结果表明:2套自动气象站数据较为完整,缺测率较低,表明自动站设备较为稳定。通过差值分析2套数据的差异,大部分要素差值小,数据一致率较高,粗差率和超差率较低,个别要素差异略大的原因可能与仪器的型号、性能有关,但检验中大多符合相应的规范要求。2套站自动观测数据可互相替代,从而保证了数据资料的完整性,大大提高了数据观测的质量。

Difference Analysis of New Type of Automatic Weather Station and Backup Weather Station Data

Using the valid data of Benxi national basic weather stations in 2014,air temperature and air pressure from the new type of automatic station and the backup of automatic station were analysed and dis?cussed,and according to the relevant standards,Benxi meteorological data were evaluated. The results show that the two sets of automatic meteorological station data is relatively complete,lack of measurement rate is low,which indicates that automatic station equipment is relatively stable. Through the analysis of the differ?ence between the difference of two sets of data,most of the elements of difference is small,the reason of the difference slightly may be associated with the performance of the instrument,most of the elements meet the requirements in the inspection. Two sets of automatic station observation data can replace each other , so as to ensure the integrity of the data,greatly improving the quality of observation data.
