Ceilometer Vaisala CL51 data, Svartberget, Sweden (SE-Svb), 2018-2024

The CL51 was designed to tackle the specific challenges of cloud height and mixing layer height, especially for high range clouds. The automated system leverages a pulsed diode lidar technology and single-lens optics to gather highly detailed measurements on multiple cloud layers — even when physical visibility is limited — so you gain the comprehensive, actionable understanding of meteorological conditions you need, exactly when you need it. Applications: • Reliable cloud detection and reporting from low-level clouds up to high-level cirrus clouds • Inputting cloud height and sky condition source data for situational awareness and numerical weather prediction models • Vertical profiling data to provide comprehensive understanding of the atmosphere all the way up to 15km • Identifying the vertical extent of aerosol layers for reliable air quality monitoring and forecasting • Automatic monitoring of boundary layer structures and verification of numerical weather forecasting and dispersion models • Supporting air quality data processing systems to study the interaction between pollutants and meteorological factors
