DZZ6型与CAWS600型自动气象站观测资料的对比分析

Comparative Analysis of Observation Data of DZZ6 and CAWS600 Automatic Meteorological Stations

为了研究DZZ6型和CAWS600型自动气象站观测资料之间的差异性,利用庆阳市西峰国家基本气象站、环县国家基本气象站、合水气象站有效数据资料,对DZZ6型ISOS软件运行的自动气象站和CAWS600型OSSMO 2004软件运行的自动气象站观测的气压、气温、湿度等资料进行气候和统计分析。结果表明:2套自动气象站数据较为完整,缺测率较低;通过差值分析2套站数据一致率较高,要素差值较小,符合相应的规范要求;检验得出用于实际业务工作的客观定量化结论,2套站自动观测数据不经序列订正就可以合并统计、互相替代;个别要素差异略大的原因可能与仪器的生产厂家、型号、性能有关,不存在系统性误差。

The paper aims to study the difference between the observation data of DZZ6 type and CAWS600 type automatic meteorological stations. The authors used the valid data of Xifeng National Basic MeteorologicalStation, Huan County National Basic Meteorological Station and Heshui County Meteorological Bureau in2014, to statistically analyze the observation data of air pressure, temperature, humidity, etc. from automaticmeteorological stations with DZZ6 ISOS software operation and CAWS600 2004 software OSSMO operation.The results showed that： the two sets of automatic meteorological station data were relatively complete, the rateof measurement lack was low. Through the difference analysis, the consistent rate of the two sets of data washigh and the difference of elements was small, meeting the code requirements. The study got the conclusionswhich were suitable for actual operation, the two sets of the observation data of automatic stations could mergestatistically and replace each other without sequence correction; the reason of the difference might beassociated with the manufacturer, model and the performance of the instrument, and there was no systematic error.
