NEw observations of the NO_y/N₂O correlation in the lower stratosphere. Geophysical Research Letters 20: doi: 10.1029/93GL03004. issn: 0094-8276.

During the Airborne Arctic Stratospheric Expedition II (AASE II), September 1991 through March 1992, in situ measurements of reactive nitrogen (NOy) and N2O were made in the Northern Hemisphere lower stratosphere. We present an analysis of this new data and compare it with results from similar data taken during AASE in the winter of 1989. In the Northern Hemisphere there is a consistent linear correlation of N2O and NOy which shows no interannual variation. Cases of departure from a linear correlation are examined and classified as being due to denitrification (NOy loss) or sampling air from a region where the photochemical lifetime of NOy is decreased. The latter case was observed for the first time in the winter of 1992. ¿ American Geophysical Union 1993
