Descripción detallada

The SkyVUE™PRO LIDAR ceilometer measures cloud height and vertical visibility for meteorological and aviation applications or long-term research applications where a high level of detail is required. Using LIDAR (LIght Detection And Ranging) technology, the instrument transmits fast, low-power laser pulses 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. The optics are immune to damage from direct sunlight.

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™PRO measures the atmosphere with high stability and repeatability, delivering excellent performance in even the harshest of conditions.

The SkyVUE™PRO provides information on cloud height, sky condition (up to five layers), vertical visibility, and raw backscatter profiles to a range of 10 km.

An automated Mixing Layer Height (MLH) option is available for air-quality applications. MLH is an important parameter in modelling air quality and air pollution episodes. The MLH is determined based on the operational algorithm used by KNMI, which detects the top of boundary layers.

The algorithm runs within the SkyVUE™PRO itself, and the results are incorporated in data messages, making it easy to incorporate the MLH into whatever systems are already in use without the need to run external special software. If you require the MLH option, please contact us.

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™PRO can be tilted at various angles 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 two-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. 

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, and scatter profiles. All can be displayed simultaneously or separately with ranges and time scales.

SkyVUE PRO-CS135-OS v.14 (429kb) 11-12-2019

Campbell Scientific has introduced a new operating system, OS14 for the SkyVUE PRO and CS135 ceilometer. It is fully backwards compatible. OS14 is available free of charge and can be downloaded from the Campbell Scientific website or supplied by email on request.

Upgrade to OS14 is recommended.


OS14 has introduced improvements to overlap functions, cloud detection filters and thresholds to reduce false cloud detection at low and medium heights notably to about 1,000m.

OS14 has increased low level vertical visibility performance and stability 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.

OS14 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 earlier operating systems. OS14 is pre-configured for Meteorological use in newly purchased SkyView PRO sensors or when OS14 is loaded onto a SkyView PRO or CS135 running earlier operating systems. 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.

OS14 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.

OS14 now has a wider range of height offsets to allow greater correction of the height of the sensor than previous OS versions.


OS14 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.

OS14 also includes improved backscatter filtering to reduce the possibility of noise banding when observed with Viewpoint

OS14 supersedes OS13 which had the above features and includes further optimised control of the dirty windows LED.

  1. In the unlikely event that a warning or an alarm is issued, the warning flag output indicates the nature of any fault.

    Few warnings or alarms are actionable by the user—except, for example, the dirty photo-diode and Laser windows alarm. Other alarms may indicate a failure requiring work that cannot be performed by the user.

  2. Some alarms, such as the tilt-angle and low-power battery shutdown voltages, are configurable. Most parameters are not configurable because they relate to the internal safe functioning of the ceilometer.

  3. Warnings are identified by the instrument when system parameters go beyond the optimum manufacturer-defined range, but where this does not prevent the operation of the sensor. An example of this is a temperature that is non-critically beyond its normal range.

    Note: For some warnings, you might not be able to take corrective action yourself.

  4. Alarms are identified by the instrument if a self-test parameter goes beyond the range of a user-defined or manufacturer-defined setting.

    Examples of manufacturer-defined settings include temperatures and circuit power. Alarms arise when a fault is identified that prevents measurements from being taken.

    User-definable alarms include tilt-angle and lead-acid battery shut-down voltage. If the ceilometer senses that these are out of range, it will report alarms in the message string, as well as in the Alarm Flag section of each message.

  5. The CS135 has LED indicator lights that flash to indicate normal or fault statuses.

    • 1 flash every 10 seconds = OK, no fault
    • 2 flashes every 10 seconds = warning (possible degraded performance)
    • 3 flashes every 10 seconds = alarm (measurements not possible)

    The output messages also contain information about Warnings and Alarms, known as the WA output. This is a single character with one of the following values:

    • 0 = No alarm or warning
    • W = Warning
    • A = Alarm

    W or A are output in the message strings when necessary.

    The description of the warning or alarm is obtained from the fault Flag code at the end of each message.

  6. The cloud ceiling height relates to the height of the base of the cloud where the sky is overcast or has broken cloud cover.

  7. Cloud height

    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.

    Cloud layers

    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.

    Cloud base

    The cloud base is the lowest part of a cloud that passes overhead. It is typically measured with a ceilometer.
