KNMI UV-polarisation lidar Ascension Island initiative (ASCII) campaign data

A ground-based UV-polarisation lidar was deployed to infer cloud droplet sizes and droplet number concentrations near the cloud base of cumulus clouds over Ascension Island. The measurements were part of the 2016 en 2017 ASCII campaigns to study aerosol-cloud interactions in the stratocumulus to cumulus transition zone of the southeast Atlantic Ocean. Measurements of uncalibrated attenuated backscatter were acquired at 30 seconds and 15 meters resolution.
