WebThe use of transmitted light within the visible spectrum allows this type of instrument to most accurately simulate human perception of visibility. The range of visibility for which a measurement can be derived is typically between 15/20 m and 20/30 km with an accuracy up to 10 km of +/- 10%. A typical instrument is illustrated below: A typical ... WebIn aviation, it is helpful for pilots to know the cloud ceiling, which is the distance between the ground and lowest cloud. The simplest way to measure this is by using a spotlight to shine a beam of light up at the clouds and measuring the angle between the ground and where the beam hits the clouds.

Cloud - Wikipedia
A cloud base (or the base of the cloud) is the lowest altitude of the visible portion of a cloud. It is traditionally expressed either in metres or feet above mean sea level or above a planetary surface, or as the pressure level corresponding to this altitude in hectopascals (hPa, equivalent to the millibar). WebCloud height is the distance between the base of the cloud and the top of the cloud, which is also called cloud thickness or cloud depth. Cloud level is the altitude at which the clouds are located according to cloud base, expressed as a range, for example, between 2 and 5 km above the ground or the sea level. WebQuestion.
