On March 28, 2025 at 16:00, a dataset of Rayleigh-Brillouin spectrum of the atmosphere at different altitudes was measured at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (31.39°N, 121.26°E).

The dataset RBS_data contains Rayleigh-Brillouin spectra at different altitudes obtained by processing the original data measured by the coherent high-spectral-resolution lidar proposed by us on March 28, 2025, at 16:00 at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (31.39°N, 121.26°E) with the noise removal and frequency response correction algorithms proposed by us. The range resolution is 75 meters.
