The greatest horizontal distance at which selected objects can be seen and identified or its equivalent derived from instrumental measurements.

The distance at which prominent unlighted objects may be identified by day and prominent lighted objects may be identified by night. abbreviation: VIS Fr: visibilit

The greatest distance that prominent objects can be seen and identified by unaided, normal 20/20 eyesight.

The greatest distance at which it is possible with the unaided eye to recognize a prominent dark object against the horizon sky. At night, it is defined as the greatest distance at which a moderately intense, unfocused light source can be seen on the horizon.

The degree to which an object (including symbols and alphanumeric characters) can be distinguished from its background; factors affecting visibility of an object include its size, contrast, level of illumination, and exposure time. See Legibility, Readability.

The distance a diver can see underwater measured in feet or meters

The quality of a letter, number, graphic, or symbol, which enables the observer to distinguish it from its surrounds or background.

The distance over which an observer can see and clearly identify an object.

greatest distance from an observer that a permanent, identifiable object can be seen by unaided, normal eyes.

the distance one can see horizontally based on seeing and recognizing such objects as buildings, bridges, or other landmarks. The reported visibility is the greatest distance the observer can see in sectors which make up at least one half of the circle of the horizon.

The visibility is a measure of the distance that one can make out objects, measured in metres or kilometres. Rain, haze, mist and fog are non-exclusive weather-based factors that reduce visibility. Air-borne dust and some kinds of pollution may also reduce visibility (see volatile organic compounds)

Visibility is defined as the greatest distance at which an object of specified characteristics can be seen and identified with the unaided eye in any particular circumstances, or, in the case of night observations, could be seen and identified if the general illumination were raised to the normal daylight level.

The ability to see and identify objects at different distances. Visibility reduction from air pollution is often due to the presence of sulfur and nitrogen oxides, as well as particulate matter.

Greatest distance at which a black object of suitable dimensions can be seen and recognized against the horizon sky, or, in the case of night observations, could be seen and recognized if the general illumination were raised to the normal daylight level.

A measurement of how clear the atmosphere is. Visibility is the greatest distance from which a person can see large objects using normal eyesight.

The greatest distance an observer can see and identify prominent objects.

the greatest distance toward the horizon that prominent objects can be identified visually with the naked eye

The greatest distance at which one can see and identify objects.

The distance at which a given standard object can be seen and identified with the unaided eye

the distance, measured in terms of depth, that you can see into a body of water; is directly affected by water clarity.

The horizontal distance an observer can see and identify a prominent object.

Broadly, the distance to which an observer can distinguish objects from their background. The concept may apply to both air and water. The determinants of visibility include the characteristics of the target object (shape, size, color, pattern), the angle and intensity of sunlight, the observer's eyesight, and the extent of light absorption and scattering caused by air and water contaminants.

The distance that atmospheric conditions allow a person to see at a given time and location. Visibility reduction from air pollution is often due to the presence of sulfur and nitrogen oxides, as well as particulate matter.

the distance over which objects can be seen

The distance a diver can see underwater measured in feet. Normally vertically not up and down.

Distance toward the horizon that objects can be seen and recognized. Smoke, haze, fog, and precipitation can hinder visibility.

the greatest distance that prominent objects can be seen and identified by unaided, normal eyes. Russian translation prepared by Nina A. Zaitseva for the Arctic Climatology Project Arctic Meteorology and Climate Atlas.

A measure of the opacity of the atmosphere, and therefore, the greatest distance one can see prominent objects with normal eyesight. The National Weather Service has various terms for visibility. Surface visibility is the prevailing visibility determined from the usual point of observation. Prevailing visibility is considered representative of visibility conditions at the station. Sector visibility is the visibility in a specified direction that represents at least a 45 degree arc of the horizon circle. Tower visibility is the prevailing visibility determined from the airport traffic control tower (ATCT) at stations that also report surface visibility.

When evaluating garment colors for safety applications, visibility refers to the color of a garment fabric in brightly lit and dimly lit situations, as well as the difference in color between the fabric and the background; refers to the ability to see through a faceplate in an encapsulated suit.

In meteorology, visibility is a measure of the distance at which an object or light can be seen. It is important to all forms of traffic: roads, sailing and aviation. Meteorological visibility refers to transparency of air: in dark, meteorological visibility is still the same as in the same air in daylight.

The ability to access or view pertinent data or information as it relates to logistics and the supply chain.
