How can you calculate the visibility?

Visibility can be calculated using various methods, typically involving measurements of light transmission or atmospheric conditions. A common approach is to measure the distance at which a known object can be clearly seen, often expressed in meters or kilometers. Meteorological instruments, such as transmissometers, can also quantify visibility by assessing the amount of light scattered by particles in the air. Additionally, visibility can be estimated using weather conditions, such as humidity and precipitation, which affect atmospheric clarity.
