Description:As a major sink of atmospheric nitrogen oxides (NO x=N O+N O 2), nitrate (NO 3/C0) in polar snow can re flect the long-range transport of NO xand related species (e.g., peroxyacetyl nitrate). On the other hand, because NO 3/C0in snow can be photolyzed, potentially producing gas phase NO xlocally, NO 3/C0in snow (and thus, ice) may re flect 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/C0to determine the degree to which local processes in fluence atmospheric and snow NO 3/C0. Based on snow and atmospheric observations during May –June 2010 and 2011, we find no connection between the local atmospheric
