description |
International audience Variations in the stable oxygen isotope composition of atmospheric nitrate act as novel tools for studying oxidative processes taking place in the troposphere. They provide both qualitative and quantitative constraints on the pathways determining the fate of atmospheric nitrogen oxides (NO + NO 2 = NO x ). The unique and distinctive 17 O-excess (Δ 17 O = δ 17 O - 0.52 × δ 18 O) of ozone, which is transferred to NO x via oxidation, is a particularly useful isotopic fingerprint in studies of NO x transformations. Constraining the propagation of 17 O-excess within the NO x cycle is critical in polar areas where there exists the possibility of extending atmospheric investigations to the glacial/interglacial time scale using deep ice core records of nitrate. Here we present measurements of the comprehensive isotopic composition of atmospheric nitrate collected at Dome C (East Antarctic plateau) during the austral summer of 2011/12. Nitrate isotope analysis has been here combined for the first time with key precursors involved in nitrate production (NO x , O 3 , OH, HO 2 , RO 2 , etc.) and direct observations of the transferrable Δ 17 O of surface ozone, which was measured at Dome C throughout 2012 using our recently developed analytical approach. Assuming that nitrate is mainly produced in Antarctica in summer through the OH + NO 2 pathway and using concurrent measurements of OH and NO 2 , we calculated a Δ 17 O signature for nitrate in the order of (21-22 ± 3) ‰. These values are lower than the measured values that ranged between 27 and 31 ‰. This discrepancy between expected and observed Δ 17 O(NO 3 - ) values suggests the existence of an unknown process that contributes significantly to the atmospheric nitrate budget over this east Antarctic region. |
