Ship-based measurements of ice nuclei concentrations over the Arctic, Atlantic, Pacific and Southern oceans

André Welti et al.

Data sets

Shipborne Ice Nucleating Particle (INP) measurements in the Arctic during PS106.1 and PS106.2 M. Hartmann, X. Gong, A. Welti, and F. Stratmann

Short summary
Ship-based measurements of maritime ice nuclei concentrations encompassing all oceans are compiled. From this overview it is found that maritime ice nuclei concentrations are typically 10–100 times lower than over continents, while concentrations are surprisingly similar in different oceanic regions. The analysis of the influence of ship emissions shows no effect on the data, making ship-based measurements an efficient strategy for the large-scale exploration of ice nuclei concentrations.
