Fluxes of nitrates between snow surfaces and the atmosphere in the European high Arctic
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-Ålesund, Svalbard as part of the EU project "`The NItrogen Cycle and Effects on the oxidation of atmospheric...

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-Ålesund, Svalbard as part of the EU project "`The NItrogen Cycle and Effects on the oxidation of atmospheric trace species at high latitudes' (NICE). At this coastal site close to the unseasonably unfrozen fjord, of the measured nitrogen species, only HNO 3 showed a significant flux on to the snow surface; a mean deposition of -8.7 nmol h -1 m -2 was observed in late April / early May 2001. These fluxes may be due to the reaction of HNO 3 with sea salt, and especially NaCl, or may be simply uptake of HNO 3 by ice, which is alkaline because of the sea salt in our marine environment.
