A device that measures the altitude of the cloud base, especially above an airfield
a device using a laser or other light source to determine the height of a cloud base An optical ceilometer uses triangulation to determine the height of a spot of light projected onto the base of the cloud; a laser ceilometer determines the height by measuring the time required for a pulse of light to be scattered back from the cloud base
A device used to evaluate the height of clouds or the vertical visibility into a surface-based obscuration
An automatic device for measuring and recording the height of clouds by projecting a modulated beam of light onto a cloud base, receiving the reflection of light through a photoelectric apparatus and computing the height by triangulation
