METHOD AND SYSTEM FOR DETERMINING ATMOSPHERIC TRANSPARENCY Russian patent published in 2018 - IPC G01W1/00 

FIELD: meteorology.

SUBSTANCE: group of inventions relates to the method and system for determining the atmosphere transparency as well as to a computer-readable data carrier, and may be used in meteorology, aviation and video surveillance. Method for determining atmospheric transparency, as well as a system for determining atmospheric transparency and a computer-readable data carrier, involves receiving optical signals from entities in the surrounding environment by means of an optical sensor, determining a brightness value for at least two directions having different elevation angles at said points, and finally determining an atmospheric transparency value on the basis of a model which combines the brightness values determined in the previous step for signals arriving from directions having a certain elevation angle, with atmospheric transparency.

EFFECT: increasing the accuracy of atmospheric transparency determination using a sensor located in a set position, and in simplifying a device for determining atmospheric transparency.
