The results analysis of wind retrieval based on a new ground-based Fabry-Perot interferometer

A new three band (892.0nm, 557.7nm and 630.0nm) Fabry-Perot interferometer (FPI) was developed by National Space Science Center (NSSC) Chinese Academy of Sciences for the observation of wind at ~87 km、~96 km and 250 km. The FPI suppresses stray light through structural design and optical design to observe wind with high precision even though under the influences of lamplight or other artificial light. The FPI located to observe wind during 19th July 2023-14th September 2023 at Xinglong site (40.40 °N, 117.59 °E), which obtained about 15 clear days’ data. The observation results of the FPI were compared with the KEO FPI. The averaged wind error deviation of the 557.7nm airglow is 4.749 m/s, the averaged wind error deviation of the 630.0nm airglow observation is 9.77m/s, and the averaged wind error deviation of the 892.0nm airglow observation is 9.45m/s.
