Lidar Ceilometer CL61
Get to know the first-of-its-kind sensor combining standard ceilometer measurements with advanced depolarization and particle differentiation.

Revolutionary depolarization
CL61’s unique depolarization capability provides outstanding benefits unavailable with any other ceilometer:
- Differentiates liquid and solid cloud and precipitating particles
- Detects the melting layer
- Allows tracking of dust, sand, and volcanic ash layers
- More accurately resolves mixed aerosol layers in the boundary layer Improves general understanding of atmospheric conditions
To do this, CL61 uses attenuated backscatter profiles measured in two polarization directions to calculate the depolarization ratio. Its optical system allows for a high signal-to-noise ratio and enables reporting of detailed vertical profiles for the full range, up to 15.4 km (9.6 mi).
Today, CL61 is widely trusted and used for some of the most innovative aviation applications, including real-time monitoring of ongoing volcanic activity and comprehensive windshear solutions.
