Fluxes of nitrates between snow surfaces and the atmosphere in the European high arctic
International audience Measurements of atmospheric and snow mixing ratios of nitrates and nitrites and their fluxes above the snow surface were made during two intensive campaigns during spring time 2001 at Ny-Alesund, Svalbard as part of the EU project ``The NItrogen Cycle and Effects on the oxidat...
