E-Profile reprocessing of ALC calibration constants for CHM15k and Mini-MPL instruments

Dataset containing the calibration constants for the EUMETNET's E-Profile ALC network. It contains the Rayleigh calibration constant as well as the new daily, Kalman filtered calibration constant for the period 2020-01-01 to 2025-12-31. It was used to recalibrate the CHM15k and Mini-MPL attenuated backscatter measurements on the period 2024 and 2025. The original measurements are archived at CEDA: EUMETNET (2026): EUMETNET E-PROFILE: ceilometer cloud base height and aerosol profile data from a network covering most of Europe with additional sites worldwide.
