Ice nucleating particles in the Canadian Arctic ...
Ice nucleating particles (INPs) in the Arctic can influence climate and precipitation in the region; yet our understanding of the concentrations and sources of INPs in this region remain uncertain. The following dissertation investigates 1) the properties and concentrations of INPs in the sea surfac...

Ice nucleating particles (INPs) in the Arctic can influence climate and precipitation in the region; yet our understanding of the concentrations and sources of INPs in this region remain uncertain.
