Improving airport operations with precise vertical profiling data and innovative precipitation and particulate differentiation.
To protect people and maintain operational continuity, modern airports depend on detailed, accurate insights about atmospheric conditions. Increased weather severity and flight frequency make these insights more crucial than ever.
Vaisala’s Ceilometer CL61 enables airports and other aviation stakeholders to detect much more than cloud height, amount, and vertical visibility. Its advanced depolarization capabilities detect other important phenomena that can impact aviation safety and efficiency:
CL61’s unique depolarization capability provides outstanding benefits unavailable with any other ceilometer:
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.
Get comprehensive profiling data 24/7—even in the harshest weather conditions—that goes beyond standard cloud height measurements to help airports and airlines operate with greater safety.

Ceilometers are robust and cost-effective lidar-based remote sensing instruments. In addition to their traditional use in detecting cloud base heights in aviation, ceilometers are increasingly used for vertical atmospheric profiling for several applications.
Vaisala introduces the depolarization measurement capability to a high-end profiling ceilometer, setting a new standard in analysis and applications.
Airports need more detailed and accurate information than ever on atmospheric conditions to help ensure flight safety. With the new Vaisala CL61 Ceilometer, you can detect much more than cloud height, amount and vertical visibility.
Vaisala ceilometers detect smoke originating in North America that travel all the way to Europe and form large smoke plumes when the winds blow from certain appropriate direction.
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.
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.
Get to the know the first-of-its-kind sensor combining standard ceilometer measurements with advanced depolarization and particle differentiation.
CL61 provides value no other ceilometer can — improving forecasting and the effectiveness of meteorological agencies.
Unrivaled visibility into atmospheric boundary layer (ABL) and pollutants improves urban and industrial projects anywhere.
