Type:
Technical instrument(s)
Description of the instrument:
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

Geographic description:
The Svartberget site (64°15′N, 19°46′E, 270 m asl) is located about 60 km west of Umeå. General The Svartberget site is located in the Svartberget Experimental Forest. The experimental forest covers 1076 ha of boreal forest land and governs a manifold of research activities since 1923. A reference monitoring program of climate and water is active since 1980. The site was established for ICOS Sweden in 2011 and hosts a Class 2 combined Ecosystem and Class 1 Atmosphere station. The research site which is co-located with the national infrastructures SITES and ACTRIS Sweden. The ACTRIS activities at Svartberget are operated by SLU.
