Abstract:

Possible deviations of a laser beam from the detector in the case of slant propagation paths are calculated with the use of measured profiles of air temperature in the atmospheric boundary layer. The possible seasonal and diurnal dynamics of the deviations under the effect of regular refraction is considered. The cases of simultaneously strong (regular) refraction of the laser beam and significant beam broadening due to the effect of turbulence are revealed and analyzed.

Keywords:

atmosphere, sounding, laser radiation, refractive index, refraction, sodar, turbulence, laser beam broadening
