Ice nucleating particle concentrations by droplet freezing assay measurements from the B17 ice core, Greenland, dating from 1370 to 1990

The data set reports on measurements of ice nucleating particles (INPs) from an ice core in Greenland (B17, 72.25, -37.25, 2820 m AMSL) that dates back to about 1370. INP measurements were performed using the FRIDGE INP counter as a droplet freezing assay for N = 135 meltwater samples from the core. From each sample 3 x 65 droplets of melt water (2.5 µL) were pipetted onto a sample substrate. The experimental nucleation temperature T was decreased at 1 °C/min until every droplet was frozen. The frozen fraction (FF) as a function of T is used to calculate the INP abundance per mL of melt water. A conversion factor is used to estimate atmospheric INP concentrations. The typical time coverage of a sampe is in the order of a couple of months. Samples were selected in regular time intervals of 10 years, plus a number of additional samples. This data supplement is related to a scientific publication (doi:10.5194/acp-2020-556).
