Composition of firn air at the H72 ice core site, Antarctica ...
Histories of atmospheric N2O concentration and its d15N and d18O were reconstructed on the basis of the analyses of firn air collected at the H72, Antarctica. The N2O concentration increased from 297 ppbv in 1975 to 314 ppbv in 1998, which reasonably agrees with the results from atmospheric observat...
