Analysis of nitrate in the snow and atmosphere at Summit, Greenland: Chemistry and transport
International audience As a major sink of atmospheric nitrogen oxides (NO x = NO + NO 2 ), nitrate (NO 3 - ) in polar snow can reflect the long-range transport of NO x and related species (e.g., PAN).

description |
International audience As a major sink of atmospheric nitrogen oxides (NO x = NO + NO 2 ), nitrate (NO 3 - ) in polar snow can reflect the long-range transport of NO x and related species (e.g., PAN). On the other hand, because NO 3 - in snow can be photolyzed, potentially producing gas-phase NO x locally, NO 3 - in snow (and thus, ice) may reflect local processes. Here we investigate the relationship between local atmospheric composition at Summit, Greenland (72°35’N, 38°25’W) and the isotopic composition of NO 3 - to determine the degree to which local processes influence atmospheric and snow NO 3 -. Based on snow and atmospheric observations during May-June 2010 and 2011, we find no connection between the local atmospheric concentrations of a suite of gases (BrO, NO, NO y , HNO 3 and nitrite (NO 2 - )) and the NO 3 - isotopic composition or concentration in snow. This suggests that 1) the snow NO 3 - at Summit is primarily derived from long-range transport and 2) this NO 3 - is largely preserved in the snow. Additionally, three isotopically distinct NO 3 - sources were found to be contributing to the NO 3 - in the snow at Summit during both 2010 and 2011. Through the complete isotopic composition of NO 3 - , we suggest that these sources are local anthropogenic particulate NO 3 - from station activities (δ 15 N = 16‰, Δ 17 O = 4‰ and δ 18 O = 23‰), NO 3 - formed from mid-latitude NO x (δ 15 N = -10‰, Δ 17 O = 29‰, δ 18 O = 78‰) and a NO 3 - source that is possibly influenced or derived from stratospheric ozone NO 3 - (δ 15 N = 5‰, Δ 17 O = 39‰, δ 18 O = 100‰). |
