Cloud Height Measurement 

 
Vaisala offers its second generation single lens ceilometer, the CL31, for unsurpassable performance in accurate cloud height measurement. The speed in measurement by the Vaisala Ceilometer CL31 enables the detection of thin cloud layers below a solid cloud base. It is able to detect three cloud layers simultaneously. The CL31 provides data on cloud hits, status and backscatter profile, for data visualization and research purposes.

The CL31 is ideal for aviation as well as meteorological applications where reliable detection of clouds is essential.

The CL31 employs pulsed diode laser LIDAR (light detection and ranging) technology, where short, powerful laser pulses are sent out in a vertical or near-vertical direction. The reflection of light (backscatter) caused by clouds, precipitation or other obscuration is analyzed and used to determine the cloud base height.

With over 5,000 installed worldwide, the Vaisala ceilometer is a field-proven and popular laser ceilometer for measuring cloud height and vertical visibility.

CL-VIEW
Vaisala also offers the Graphical User Interface for Ceilometers CL-VIEW. CL-VIEW is an independent data collection, storage, and presentation program designed for Vaisala's Laser Ceilometers CL31, CT25K, CT75K. The Ceilometer model CT12K is also partially supported.

Ceilometers

Vaisala provides high quality ceilometers which measure cloud heights at 25,000 feet or 40,000 feet. These sensors offer a superior measurement accuracy which has been documented in international intercomparisons.
