The SkyVUE™8 LIDAR Ceilometer is ideal for measuring cloud base heights and vertical visibility at airports, helipads (onshore or offshore), and other meteorological applications. The SkyVUE™8 measures the atmosphere with high stability and repeatability, providing you with information on cloud base heights, sky condition (up to five layers), vertical visibility, and raw backscatter profiles. Notably, the ceilometer meets or exceeds all the necessary ICAO, CAA, and WMO requirements and recommendations.
Because of its robust construction, the SkyVUE™8 only requires minimal maintenance and can be continuously used in either static or mobile applications in harsh environments. Its compact design and low weight of 18 kg make it easy to transport and deploy.
With an operational reporting range of 8 km, the SkyVUE™8 has one of the highest in its class. It is easy to use yet 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 base heights to heaters, blowers, and a sun filter for 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 and provide assurance of continuous, reliable, and accurate performance.Read More
The SkyVUE™8 LIDAR ceilometer measures cloud base heights and vertical visibility for meteorological and aviation applications. Using LIDAR (LIght Detection And Ranging) technology, the ceilometer transmits fast, low-power laser pulses (not harmful to eyes) into the atmosphere and detects backscattered returns from clouds and aerosols above the instrument.
A unique, efficient, single-lens design increases optical signal-to-noise ratio and allows 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 base heights 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 base heights, sky condition (up to five layers), vertical visibility, and raw backscatter profiles to a range of 8 km.
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 up to 24°. Tilting the SkyVUE™ by even a few degrees can be 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 two-axis inclinometer provides automatic correction of cloud base heights at all angles, ensuring ease of installation and confidence that cloud base 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 visualization 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.

Campbell Viewpoint is viewing software designed to accompany the Campbell Scientific optical sensor range, including the CS135 ceilometer, SkyVUE PRO, SkyVUE 8, SkyVUE 8M, CS120A visibility and CS125 present weather sensors. It is free to download (or via email on request) and use for 100 hours, after which you will need to purchase a key to continue using it.
Viewpoint version 22.214.171.124 has introduced our new ceilometer sensors to the list of instruments that can be monitored. This includes the SkyVue PRO, SkyVUE 8 and SkyVUE 8M.
Previous sensors are still available.
Version 126.96.36.199 also includes some minor bug fixes and improvements to the help menu.
Campbell Scientific has introduced a new operating system, OS2 for the SkyVUE 8 ceilometer. It is fully backwards compatible. OS2 is available free of charge and can be downloaded from the Campbell Scientific website or supplied by email on request.
Upgrade to OS2 is recommended.
OS2 has introduced improvements to optical overlap functions, cloud detection filters and the filter thresholds to reduce false cloud detection at low to medium heights notably up to about 1,000m.
OS2 has increased performance in estimating low level vertical visibility particularly from the ground to 50m.
An option “cloudMode A“ has been added to only report the highest cloud seen during precipitation events. This has been added to further minimise the reporting of rain as low cloud.
OS2 has a new command “application n”, which allows the user to select the recommended, optimum settings for specific applications, including Aviation, Research, Air Quality and Meteorology. In addition, you can specify you own user defaults or select the original default settings for all settings as defined in OS1. OS2 is pre-configured for Aviation use in newly purchased SkyVUE 8 sensors or when OS2 is loaded onto a SkyVUE 8 running OS1. Individual user settings remain adjustable for further optimisation by the user and for use in other applications.
There is a new option to allow the user to select whether backscatter rolling averages are calculated as mean or median values. The median option is new and is more effective at removing transient signals caused by birds and insects. A new parameter has been added in the BS command to permit users to select either option. Other commands affected include “getuser” and “setuser”.
A “mainsFail” flag has been added to the output messages to indicate failure of mains power whilst operating on the backup battery.
OS2 has introduced a global ID (address) of “99” to permit users to connect to the instrument over a serial connection, if the ID is unknown.
A command “loados” has been added to make it easier to load a full new operating system. The selection of specific individual board operating systems, DSP, TOP and PSU, can still be performed and “loados 4” will continue to function, as in previous OS versions.
OS2 now has a wider range of height offsets to allow greater correction of the height of the sensor than previous OS versions.
OS2 includes changes to Sky Condition to improve weighted average cloud heights and prevent the small possibility for arithmetic overflow which may result in a spurious layer being reported.
OS2 also includes improved backscatter filtering to reduce the possibility of noise banding when observed with Viewpoint.
