“…The information obtained in the past half of the 20-th century was given in [9]. Our measurements on different days without filters showed that the degree of linear polarization (DLP) at the zenith of the sky is 30-70% [10]. This is much less than the DLP value for pure gas atmospheres, which often goes up to 100%.…”

Earth’s climate changes are the result of natural changes in the energy balance of Sun irradiation and influence of anthropogenic factors on the variations of ozone layer thickness and stratospheric aerosol abundance. It is developed a miniature polarimeter for satellite polarimetric experiments in the ultraviolet region of the sunlight spectrum. The main task of this device is to the obtain an information on the stratospheric aerosol physical properties. We tested this polarimeter on a bench specially designed and manufactured as well. It is possible to measure by it the phase dependences of the degree of linear polarization (DLP) of solar radiation scattered by the Earth’s atmosphere. A set of special computer programs was developed for comparing the spectral polarimetric measurements DLP data of cloudless sky with model calculations of DLP for the artificial gas-aerosol medium. Thus, the prototype of satellite polarimeter as well as special computer programs make it possible to study the Earth’s atmosphere aerosol physical characteristics.

“…At the beginning of operation, the useful signal stream was about 300 k pulses per second with a dark stream of no more than 20 pulses per second. The results of obtained observations [10], as well as the additional results [20] can be used for analysis and subsequent processing.…”

“…The Main Astronomical Observatory (MAO) of the National Academy of Sciences of Ukraine (NASU) proposed in 2004 to conduct a space experiment to study the physical characteristics of the stratospheric aerosol from the spacecraft [21]. For this a working model of an on-board ultraviolet polarimeter (UVP) was developed and created together with Igor Sikorsky KPI and Lviv Polytechnic National University [25,26]. This optoelectronic device can receive polarimetric data during remote sensing of a stratospheric aerosol from a spacecraft.…”

“…To test the proposed methodology for carrying out polarization observations of a cloudless sky (measuring from "bottom") from a telescope a modification of the UVP model was used [11,25,26,28,29]. This model was carefully studied on the above-mentioned stand, specially adapted for this purpose.…”

Climate changes on planet Earth are mainly caused by disturbances in the energy balance of the Sun-Earth system. This process is the result of both natural changes in nature and the influence of anthropogenic factors. The combined effect of these factors can lead to threatening phenomena for mankind - a decrease in the power of the ozone layer, the formation of “ozone holes” and global warming on the planet and other disasters. The study of the causes of these factors and the determination of their relative contribution is one of the pressing problems of our time.
