FIELD: physics.
SUBSTANCE: disclosed is method of determining of icing atmospheric potential. Method comprises transmitting (304) of Doppler heterodyne LIDAR (instrument light detection and determination of distance) (108a, 108b) of electromagnetic radiation into atmosphere and reception of radiation scattered from aerosol, in particular, from clouds. Determination (306) of signal intensity indication, in particular SNR-ratio (ratio of signal-noise ratio at carrier frequency), based on received scattered signal for one or more distances, in particular altitude above specified base level, in particular above LIDAR location. Compared (308) indicating intensity of signal with at least one preset basic value in order to obtain value of probability of presence of cloud (110) on specified one or more distances. Determined (310) value of potential icing on said several distances based on said comparison and temperature value on specified one or more distances. Disclosed is system for implementing said method.
EFFECT: technical result is increase of accuracy of determining of icing atmospheric conditions.
