WebIn this Letter, we report on a novel method for measuring atmospheric temperature profiles by lidar during daytime for heights of 2–15.3 km, with a vertical resolution of 0.3–2.2 km, using Rayleigh–Brillouin scattering. WebSpontaneous Rayleigh‐Brillouin scattering spectra in nitrogen have been measured in the pressure range from 4 to 7 bar at a wide temperature from 291 to 399 K with a scattering angle of about 90°, and then fitted to different theoretical models (S6, V3, and G3). The result of the root‐mean‐square errors of fitting residuals shows that the V3 and G3 models have …
