Short summary

This study provides a unique framework for assessing aerosol hygroscopicity by combining Raman lidar observations with vertically resolved in situ measurements from the balloon-borne Compact Backscatter Aerosol Detector coupled with Vaisala RS41 radiosondes and ground-based tandem nephelometers. The three approaches showed good agreement. Raman lidar identified more than 200 hygroscopic aerosol layers, constituting one of the largest datasets available for statistical investigations.
