In the absence of particles such as aerosols and clouds (typically above 30 km), the number of photons collected on the lidar receiver is proportional to the number of backscattering air molecules.

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 … The Rayleigh flow model begins with a differential equation that relates the change in Mach number with the change in stagnation temperature, T0. The differential equation is shown below. $${\displaystyle \ {\frac {dM^{2}}{M^{2}}}={\frac {1+\gamma M^{2}}{1-M^{2}}}\left(1+{\frac {\gamma … See more Rayleigh flow refers to frictionless, non-adiabatic flow through a constant area duct where the effect of heat addition or rejection is considered.
