Abstract
<strong class="journal-contentHeaderColor">Abstract.</strong> We present a global multiyear height-resolved data set of aerosol-type-specific cloud condensation nuclei concentrations (<em>n</em><sub>CCN</sub>) estimated from the spaceborne lidar aboard the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite. For estimating <em>n</em><sub>CCN</sub>, we apply the recently introduced Optical Modelling of the CALIPSO Aerosol Microphysics (OMCAM) algorithm to the CALIPSO level 2 aerosol profile product. The estimated <em>n</em><sub>CCN</sub> are then gridded into a uniform latitude-longitude grid of 2° × 5°, a vertical grid of resolution 60 m from the surface to an altitude of 8 km, and a temporal resolution of one month. The data spans a total of 186 months, from June 2006 to December 2021. In addition, we provide a 3D aerosol-type-specific climatology of <em>n</em><sub>CCN</sub> produced using the complete time series. We further highlight some potential applications of the data set in the context of aerosol-cloud interactions.
