Ceilometer
A Ceilometer is a device using a laser or other light source to determine the height of a cloud base.
ceilometer"An automatic, active, remote-sensing instrument for detecting the presence of clouds overhead and measuring the height of their bases.
ceilometer
An automatic, recording, cloud-height indicator. A light beam is projected upward on to the cloud base; the reflected light is detected by a photocell and the height is determined by triangulation.
