DeLiAn – a growing collection of depolarization ratio, lidar ratio and Ångström exponent for different aerosol types and mixtures from ground-based lidar observations

DeLiAn is a collection of lidar-derived aerosol intensive optical properties for several aerosol types. The intensive parameters are the particle linear depolarization ratio, the extinction-to-backscatter ratio (lidar ratio) and the Ångström exponent. The data collection is based on globally distributed, long-term, ground-based, multiwavelength, Raman and polarisation lidar measurements.

DeLiAn is available in two data formats: NetCDF and excel workbook. The intensive optical properties are presented at the typical lidar wavelengths, 355, 532 and 1064 nm, for 13 aerosol categories in total. The variables included in the datafiles are listed below. For each variable, a full description is provided in the long_name attribute (applicable for the netCDF file only). The same information is provided in the first excel sheet (“List of variables”).
