Аннотация:... The experiment was carried out on a slightly inclined 1350 m atmospheric path, described in detail in. 19 The data were obtained during the period from July 2016 to July 2017 under various weather conditions, including rain, snow, strong refractive noise due to convective currents and a lateral wind. As the radiation sources multimode and single-mode lasers were used, generating a continuous signal with a power up to 36 W in the near-IR range close to the atmosphere transparency window. ...
