ceil: Ceilometer

The ceilometer (CEIL) is a remote-sensing instrument that measures cloud height, vertical visibility, and potential backscatter signals by aerosols. It detects up to three cloud layers simultaneously. Operating through a maximum vertical range of 7700 m, the CEIL transmits near-infrared pulses of light and the receiver detects the light scattered back by clouds and precipitation.
