Abstract

This dataset contains backscatter profiles from the CHM15k ceilometer, a one-wavelength backscatter lidar operating at 1064 nm. It includes uncalibrated, unvalidated data reported by the instrument at 33 sites in the nationwide meteorological observing network. Retrieved cloud base heights up to 3 layers, sky condition information and aerosol layer height, based on manufacturer algorithms are included. Vertical resolution: 10 m, time resolution: 12 s.
