Atmospheric turbulence spectrum in high resolution mode detected by a High Power-Aperture sodium Lidar over Yanqing, Beijing (40.47°N, 115.97°E)

•High Power-Aperture lidar system with two wavelengths and three channels for Rayleigh scattering, Mie scattering and Na fluorescence simultaneous detecting was completed at Beijing (Yanqing District, 40.3°N, 116.2°E). The excellent detecting performance of the lidar as photon counts shows a considerable high value of which the sodium layer echo peak value can reach to more than 37000 counts.•A relevant advanced lidar detecting standard has been realized. High resolution mode (15 m, 6.7 s) has been implemented while photo count per shot reaches to a considerable high value as 861, and the Power-Aperture Product can reach to 0.7 Wm2 which is equivalent to the largest LZT lidar (6-meter diameter, 5 w power, 1500 photocount per shot, 0.6 Wm2 at UBC, Canada), ALO (1000 photocount per shot 0.6 Wm2 at Cerro Pachón, Chile) and STAR (Boulder, Colorado US) lidar as their high level standard at the moment.•Based on this High Power-Aperture lidar, the first report of observations of turbulence spectrum in North hemisphere over China was provided, which had been extremely difficult to be observed due to the resolution and the signal/noise rate as in before for most researches. The observed turbulence spectrum was found in consistent with the only report by ALO lidar at Chile in South hemisphere observed in 2017 [Y. Guo et. al., Geophys.Res.Lett.,2017] and well fitted with the theory prediction, which can effectively help us to further understand the entire global gravity wave behavior.
