दृश्यता क्या है?

Visibility is measured in metres or kilometres at weather stations using reference points at known distances. Fog reduces visibility below 1 km. Mist is 1–5 km. Haze from pollution or fires can reduce visibility to 2–5 km across wide areas. Visibility below 550 metres triggers aviation fog warnings.
