Lidar ceilometer (CL61) measurements of attenuated backscatter coefficient and linear depolarisation ratio in summertime in Narsaq, South Greenland during Greenfjord 2023

Abstract and dataset contents: This dataset contains atmospheric profiles of attenuated backscatter coefficient and linear depolarization ratio measured with a lidar ceilometer CL61 (Vaisala, Finland) during the GreenFjord campaign from June to August 2023 in Narsaq, Greenland. Measurements were carried out at the Narsaq International Research Station (NIRS) in southern Greenland (60.9158°N, 46.0533°W, 17 m above sea level). Full description of the dataset and the cleaning procedure for the data can be found in the Metadata_CL61.docx file. Briefly, the dataset file (CL61_GF.nc) consists of a netcdf file which includes: Datetime Measured distance from the instrument in the direction of the transmitted laser beam Attenuated backscatter coefficient (raw) Attenuated backscatter coefficient (clean) Linear depolarisation ratio (raw) Linear depolarisation ratio (clean) Funding acknowledgements: This work was supported by funding from the Swiss National Science Foundation grant no. 200021_212101, the Swiss Polar Institute grant no.
