LIDAR MEASUREMENTS OF OPTICAL THICKNESS OF HIGH-LEVEL CLOUDS IN TOMSK

The report presents data from lidar observations of upper-level clouds in Tomsk in 2011-2017. Observations were carried out using a LOSA-S multi-wave lidar, simultaneously recording elastic scattering signals (355 and 532 nm) and Raman scattering signals in the vibrational Q-band (387 and 607 nm). Examples of lidar records are given, the method for determining the optical thickness of the cloud layer and possible sources of calculation errors are considered.
