Variation of Ice Nucleating Particles in the European Arctic over the Last Centuries
The historical development of ice nucleating particle concentrations (NINP) is still unknown. Here, we present for the first time NINP from the past 500 years at two Arctic sites derived from ice core samples. The samples originate from the EUROCORE ice core (Summit, Central Greenland) and from the...

The historical development of ice nucleating particle concentrations (NINP) is still unknown.

No long term trend is obvious in the measured samples, and the overall range of NINP is comparable to present‐day observations.
