A historical record of changes in the N 2 O isotope composition is important for a better understanding of the global N 2 O atmospheric budget. Here we have combined measurements of trapped gases in the firn and in ice cores of one Arctic site (North GReenland Ice core Project - NGRIP) and one Antar...
