Short summary
This study presents atmospheric ice-nucleating particle (INP) data from the Gruvebadet observatory in Ny-Ålesund. A moderate summertime increase in INP levels is observed at -15 °C but not at other temperatures (-18 and -22 °C). Conversely, a marked seasonal evolution was observed for the contribution of super-micrometer INPs, which is at its maximum throughout summer up to early autumn. We show that marine biogenic INPs may be relevant in the Arctic during seasons of reduced sea ice coverage.
