Abstract

This dataset contains backscatter profiles from the CHM15k ceilometer, a single-wavelength, automatic 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.
