Cloud Height Instruments

Ceilometers are stand-alone instruments designed to measure cloud and aerosol height profiles using a laser based LIDAR (Light Detection And Ranging) technique. The light emitting component is a low power diode laser with the output power limited to an eye-safe level. They determine cloud base heights, penetration depths, mixing layer height and vertical visibilities. Within their operating range they reliably detect multiple cloud layers and cirrus clouds.

They are most commonly used as part of an AWOS system at airports where cloud height and vertical visibilities are essential to the safe operation of the air traffic systems.

The other significant use is as a networked system across a country or territory where atmospheric aerosols and cloud migration is of interest to the local meteorological community. Such studies are used for monitoring airborne pollutant origination and migration as well as its dispersal and distribution.

Biral can offer two different types of ceilometer – one for general aviation use at airports and helidecks (7.5km / 25,000 feet range) and a higher range unit for meteorological and atmospheric aerosol research (15km / 50,000 feet range), such as volcanic ash cloud monitoring.
