都江堰气象站CAWS 600S与DZZ5自动气象仪器及其观测数据对比分析

Comparative Analysis of CAWS 600S and DZZ 5 Automatic Meteorological Instruments and Observational Data in Dujiangyan Meteorological Station

[目的]为了确保气候统计资料的准确性和连续性,研究都江堰自动站CAWS 600S型与DZZ 5型的设备及其观测数据的差异。[方法]对2种自动气象站的硬件、软件、对时与采样和算法进行对比分析;对两站2015年的逐日气象观测数据进行差值平均值和超差率分析。[结果]DZZ 5型自动站的仪器更先进,2种自动气象站的观测数据存在一定的差异。[结论]DZZ 5型自动站相对CAWS 600S型自动站而言有较大的改进和创新,测量的气象数据更准确。

[Objective] The research aimed to ensure the accuracy and continuity of climatological data,the difference of equipment and its observed databetween CAWS 600 S and DZZ 5 of Dujiangyan automatic station and its observation data was studied.[Method]Two automatic weather station of hardware,software,time synchronization and sampling algorithm were compared and analyzed. On two stations in 2015 the daily observation data difference average value and ultra slip were analyzed.[Result]The equipment of DZZ 5 Automatic station more advanced than that of CAWS 600 S automatic station. There were some differences in observation data between two kinds of automatic weather stations. [Conclusion]DZZ5 type automatic station is relatively large improvement and innovation,the measurement of the weather data is more accurate and more accurate.
