The SkyVUE™8 is a generously specified ceilometer for airports, helipads (on or offshore) and meteorological applications. It meets or exceeds all the necessary ICAO, CAA and WMO requirements and recommendations.
Its robust construction requires minimal maintenance and enables continuous use in either static or mobile applications in harsh environments. Its compact design and low weight of 18 kg makes it easy to transport and deploy.
The SkyVUE™8 has an operating range of 8 km, one of the highest in its class. It is easy to use and features advanced signal processing and unique optics to provide superior resolution and performance.
The SkyVUE™8 has many standard features, from a tilting base and two-axis inclinometer for automatic correction of cloud heights. Heaters, blowers and sun filter enable operation under all conditions, making deployments possible around the world.
Unique standard features include an easy-to-operate Stratocumulus calibration, long-life back-up battery and twin clocks to augment its many continuous diagnostic self-checks, to provide assurance of continuous, reliable and accurate performance.Read More
The SkyVUE™8 LIDAR ceilometer measures cloud height and vertical visibility for meteorological and aviation applications. Utilizing LIDAR (LIght Detection And Ranging) technology, the ceilometer transmits fast, low-power laser pulses into the atmosphere and detects back-scattered returns from clouds and aerosols above the instrument.
A unique, efficient, single lens design increases optical signal-to-noise ratio allowing for larger optics in a compact package improving accuracy and measurement performance.
This approach, along with state-of-the-art electronics, provides a powerful and stable platform from which to measure cloud height and vertical visibility to high accuracy. The SkyVUE™8 measures the atmosphere with high stability and repeatability delivering excellent performance in even the harshest of conditions.
The SkyVUE™8 provides information on cloud height, sky condition (up to five layers), vertical visibility and raw backscatter profiles to a range of 8km.
The unique stratocumulus calibration capability, which allows users to calibrate measurements of scatter coefficients, uses a simple and user-friendly field method, giving complete confidence in the scatter profiles reported and removes the requirement to have the unit sent back for calibration.
Reliable range measurement is further assured by cross checking two separate internal quartz clocks, eliminating the possibility of unidentified errors due to clock drift.
The SkyVUE™8 can be tilted at various angles and up to 24°. A small tilt is important as it allows the ceilometer to resist high levels of reflection from large raindrops and frozen particles that can impair vertical type sensors. The tilt also improves rain run-off on the ceilometer window, resulting in a much higher performance compared with vertical ceilometers.
Tilting to 24° also means that it can be operated anywhere in the world without the sun shining into the lens and resulting in missing data. An internal 2-axis inclinometer provides automatic correction of cloud height at all angles, ensuring ease of installation and confidence that cloud heights are automatically corrected throughout the lifetime of the installation.
The SkyVUE™8 complies with ICAO, CAA and WMO guidance and meets or exceeds all recommendations and specifications (this includes ICAO 9837, ICAO Annex 3, CAP437 and CAP746).
Software for data visualisation and interpretation
Ceilometer data can be displayed using Campbell’s Viewpoint software or fed directly into existing data systems. The Campbell Viewpoint software will display the output from the ceilometer in a convenient and configurable form, including information on sky condition, mixing layers, scatter profiles, etc.; all can be displayed simultaneously or separately with ranges and time scales.

The cloud ceiling height relates to the height of the base of the cloud where the sky is overcast or has broken cloud cover.
Cloud height is commonly used to refer to the height of the cloud base above ground level. (This is what the ceilometer reports.) However, it can also be used to refer to the thickness of a cloud, which is the difference in height between the base and very top of the cloud. It is possible for a ceilometer to estimate the thickness of thinner clouds. Occasionally, when reporting satellite data, it can also be used to refer to the height of the very top of a cloud above ground level.
At any one time, there may be several separate layers of cloud above a point on the ground. Each of these is a cloud layer, and each is given a cloud base height when it is detected by a ceilometer. The WMO (World Meteorological Organization) has set out rules that govern the minimum vertical separation that is required between layers before reporting more than one layer of cloud.
The cloud base is the lowest part of a cloud that passes overhead. It is typically measured with a ceilometer.
