Clouds - calibrated attenuated backscatter profiles from CHM15k ceilometers in the KNMI observation network, 5 minute averaged data

This dataset contains calibrated attenuated backscatter profiles from the CHM15k ceilometer, a one-wavelength backscatter lidar operating at 1064 nm. It includes calibrated, unvalidated daily aggregated files at five sites: Cabauw, De Kooy, Groningen Airport Eelde, Maastricht Aachen Airport and Vlissingen. Level 2 data processing is performed by the Eumetnet E-PROFILE ALC data hub: https://www.eumetnet.eu/activities/observations-programme/current-activities/e-profile/. Vertical resolution 30 m, time resolution 5 minutes.
