Description
The upcoming Cherenkov Telescope Array (CTA) project is expected to
provide unprecedented sensitivity in the low-energy (<~100 GeV) range
for Cherenkov telescopes. In order to fully exploit the potential of
the telescope systems it is meaningful to look for ways to further
improve the available analysis methods and include possible biasness
of the Cherenkov images due to the influence of the atmospheric
electric processes.A LIDAR system for the continuous monitoring of the
troposphere above the CTA site is proposed as a solution of mentioned
above problem. The reflected from clouds return profiles will be
sensitive to the polarization of the elastic backscattered signal. At
present, the system is being tuned for measuring vertical atmospheric
backscatter profiles of aerosols and hydrometeors, analyze the
depolarization ratio of elastic backscattered laser beams and
investigate the influence of external factors on the beam
polarization. In this paper, we describe the first measurements of
polarization separated LIDAR return profiles and depolarization ratio
profile in the atmosphere and clouds by means of our LIDAR system.
