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.
