Data sets

Shipborne Ice Nucleating Particle (INP) measurements in the Arctic during PS106.1 and PS106.2 Markus Hartmann, Xianda Gong, André Welti, and Frank Stratmann

Short summary
Ice-nucleating particles (INPs) are not well characterized in the Arctic despite their importance for the Arctic energy budget. Little is known about their nature (mineral or biological) and sources (terrestrial or marine, long-range transport or local). We find indications that, at the beginning of the melt season, a local, biogenic, probably marine source is likely, but significant enrichment of INPs has to take place from the ocean to the aerosol phase.
