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 single-wavelength, automatic operating at 1064 nm. It includes calibrated, unvalidated files for 33 sites in the nationwide ceilometer network. Level 2 data processing is performed by the EUMETNET E-PROFILE ALC data hub. Vertical resolution: 30 m, time resolution: 5 minutes.
