The results of atmosphere laser sounding carried out in frame of round the world expedition on the board of sail training ship "Nadezhda" are presented in this work. Nd:YAG laser was operated on wavelength λ=532 nm, energy per Q-switched pulse - 0.18 J, pulse duration - 4 ns. Laser repetition frquency was 10 Hz. Photomultiplies of backscattering signal receiving system operate in photon counting and analogue mode. Spatial resolution in photon counting mode - 240 m, in analogue mode - 6 m. The night dynamics and structure of boundary layers was investigated.
