| The horizontal distance at which targets of known distance are visible over at least half of the horizon. It is normally determined by an observer on/or close to the ground viewing buildings or other similar objects during the day and ordinary city lights at night. Under low visibility condictions the observations are usually made at the control tower. Visibility is REPORTED IN MILES AND FRACTIONS OF MILES in the Aviation Weather Report. If a single value does not describe adequately describe the visibility, additional information is reported in the "Remarks" section of the report.
