扫描与全空式FPI观测数据对比分析

Observation Data Analysis by the Scanning and All-Sky FPI

法布里-珀罗干涉仪能够实现对中高层大气风场的探测。基于扫描式法布里-珀罗干涉仪对大气风场探测的可靠性与准确性,对全空式法布里-珀罗干涉仪(All-sky FPI,ASFPI)探测风场的性能进行检验。通过2015年6月在新疆进行的全空式FPI与扫描式FPI 557.7nm气辉观测对比实验,分析结果显示两者探测得到的视线风和水平风场具有较好的一致性,验证了全空式FPI测风性能的可靠性。

The Fabry-Perot interferometer（FPI） can realize the detection of the upper and middle atmospheric wind field. Based on the reliability and accuracy of the Scanning FPI（SFPI） on the detection of atmospheric wind field, the performance of the All-sky Fabry-Perot iilterferometer（ASFPI） to detect the wind field is tested. Through the contrast experiment of AS- FPI and SFPI 557.7 nm air glow observation in Xinjiang in June 2015, the analysis results show that the line of sight and horizontal wind field detected by the two are in good agreement with each other, and the reliability of the ASFPI wind per- formance is verified.
