Improving urban and industrial air quality awareness with precise cloud height and profiling data, plus advanced particulate differentiation.
Atmospheric boundary layer (ABL) assessment provides visibility into highly influential, specific weather phenomena that are often more difficult to assess and predict than broad meteorological patterns. These phenomena are especially important to air quality and pollution management.
Vaisala’s CL61 is a first-of-its-kind ceilometer, combining crucial cloud height and profile data with advanced depolarization for precipitation and particulate differentiation. This puts CL61 in a class of its own and enables agencies, governments, and companies to operate more intelligently and efficiently than ever before.
CL61 is easy to integrate, cost-effective, and backed by Vaisala’s globally trusted sensor technology and service capabilities. It has already shown itself to be a critical tool across many use cases.
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 applications, including real-time monitoring of ongoing volcanic activity and enhanced urban pollution tracking.
Air quality in cities can vary significantly due to different microclimates, pollution sources ad geographies. Watch the video for more information.
Lidar based atmospheric measurement with vertical profiling for detailed data and insights.
Learn more about the high-performance light detection and ranging (LiDAR) instrument with depolarization measurement capable of unattended operation 24/7 in all conditions.
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.
Accurate calibration is fundamental to the high measurement accuracy of Vaisala Lidar Ceilometer CL61. CL61 distance measurement is calibrated against a reference that is traceable to international standards (SI units).
Vaisala introduces the depolarization measurement capability to a high-end profiling ceilometer, setting a new standard in analysis and applications.
