Iceland is an episodic source of atmospheric ice-nucleating particles relevant for mixed-phase clouds
Ice-nucleating particles (INPs) have the potential to remove much of the liquid water in climatically important mid- to high-latitude shallow supercooled clouds, markedly reducing their albedo. The INP sources at these latitudes are very poorly defined, but it is known that there are substantial dus...
