A ceilometer is a device that uses a laser or other light source to determine the height of a cloud ceiling or cloud base. [1] Ceilometers can also be used to measure the aerosol concentration within the …

Vaisala ceilometers accurately measure ceiling or base height of cloud layers, and they leverage pulsed diode lidar technology and single lens optics. They are engineered to deliver highly accurate data on …

Campbell Scientific offers ceilometers that use lidar (light detection and ranging) technology to measure cloud height, vertical visibility, and mixing layer height.

Ceilometer, device for measuring the height of cloud bases and overall cloud thickness. One important use of the ceilometer is to determine cloud ceilings at airports.

Ceilometer is a device for determining the cloud ceiling by means of a reflected light beam. The American Meteorological Society (AMS) defines cloud ceiling as the height of the lowest opaque …

The Vaisala Laser Ceilometer (CEIL) is a self-contained, ground-based, active, remote-sensing device designed to measure cloud-base height, vertical visibility, and potential backscatter signals by aerosols.

May 29, 2024 · A ceilometer is a critical device used predominantly in meteorology and aviation to measure the height of a cloud base. This tool is essential for assessing cloud cover, which directly …

May 21, 2024 · What Is a Ceilometer? A ceilometer is an instrument most often used to indicate the current height of a cloud base. An optical ceilometer projects a modulated beam of light onto the …

Mar 8, 2025 · A ceilometer is a meteorological instrument designed to measure the height of the cloud ceiling or cloud base. It operates by emitting a powerful beam of light, modulated at an audio …

More than just a ceilometer, the Vaisala CL61 uses first-of-its-kind technology to provide refined profiling data and detect liquid/frozen depolarization, dust, and volcanic ash — in any weather, 24/7.
