Data sets

Ice nucleating particle concentrations by droplet freezing assay measurements from the B17 ice core, Greenland, dating from 1370 to 1990 Schrod, Jann; Kleinhenz, Dominik; Hörhold, Maria; Erhardt, Tobias; Richter, Sarah; Wilhelms, Frank; Fischer, Hubertus; Ebert, Martin; Twarloh, Birthe; Della Lunga, Damiano; Jensen, Camilla Marie; Curtius, Joachim; Bingemer, H G

Short summary
Ice-nucleating particle (INP) concentrations of the last 6 centuries are presented from an ice core in Greenland. The data are accompanied by physical and chemical aerosol data. INPs are correlated to the dust signal from the ice core and seem to follow the annual input of mineral dust. We find no clear trend in the INP concentration. However, modern-day concentrations are higher and more variable than the concentrations of the past. This might have significant atmospheric implications.
