Clouds - cloud base heights and backscatter profiles from CHM15k ceilometers in the KNMI observation network, 12 second instrument data
Bewolking - wolkenbasishoogten en backscatterprofielen van CHM15k ceilometers in het KNMI meetnet, 12 seconden sensordata

This dataset contains backscatter profiles from the CHM15k ceilometer, a one-wavelength backscatter lidar operating at 1064 nm. It includes daily uncalibrated, unvalidated data reported by the instrument at five sites: Cabauw, De Kooy, Groningen Airport Eelde, Maastricht Aachen Airport and Vlissingen. 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.
