Lidar Ceilometer CL61
for Meteorology

More than just a ceilometer, the Vaisala CL61 uses first-of-its-kind technology to provide refined profiling data and detect liquid/frozen depolarization, dust, and volcanic ash — in any weather, 24/7.

Redefining cloud measurement

Delivering the most comprehensive insights in the industry, CL61 is a high-performance light detection and ranging (LiDAR) instrument with depolarization measurement capable of unattended operation in all conditions.

In addition to basic ceilometer reporting, the CL61 offers depolarization measurement that enables differentiation between solid, liquid, or mixed-phase clouds and precipitation, providing ready-to-use information for atmospheric characterization.

The CL61 complements already-existing research lidars and can be added on to build hybrid ceilometer networks for more accurate weather modeling and situational awareness.

Mitigating the hazards of volcanic ash

Volcanic ash is both easily convected upward within the plume and carried downwind for very long distances. As it falls out of suspension, it can potentially affect communities across hundreds, or even thousands, of square kilometers.

Detecting volcanic ash rain in the Canary Islands

The Canary Islands, and especially the island of La Palma, has been experiencing the volcanic eruption of Cumbre Vieja since September 2021. Vaisala’s Lidar Ceilometer CL61 with depolarization capability has been measuring the volcanic ash layers aloft since end of October.
