METHOD FOR DETERMINING THE METEOROLOGICAL RANGE OF VISIBILITY IN DIFFICULT WEATHER CONDITIONS Russian patent published in 2022 - IPC G01W1/00 

FIELD: meteorology.

SUBSTANCE: invention relates to the field of meteorology and can be used to determine the meteorological range of visibility in difficult weather conditions. Essence: to implement the method, a radiating unit, a receiving unit and a computing unit are used. Moreover, the radiating unit contains a collimating lens and an LED located in the focus of the collimating lens. The receiving unit contains a photodetector and a lens whose diameter is no less than the width of the collimated light beam, focusing the attenuated radiation on the photodetector. The intensity of the noise recorded by the photodetector is measured by the receiving unit when the LED radiation is turned off. The intensity of the unabated visible light beam generated by the LED is measured by the receiving unit near the radiating unit. The receiving unit is installed at a fixed distance from the radiating unit and the intensity of the radiation attenuated by the atmospheric layer recorded by the photodetector is measured. The meteorological visibility range is calculated taking into account the measured parameters.

EFFECT: improving the accuracy of measuring the meteorological visibility range in difficult meteorological conditions.
