We survey measurements of stratospheric NOy on the NASA DC-8 during AASE II in early 1992. Emphasis is on correlations with other long-lived species: O3, N2O, and CH4. No cases of extremely high NOy/O3 ratios were seen in 1992. This suggests that denitrification at higher altitudes was less pervasive than in 1989. Values of NOy/O3 in 1992 are comparable to, though perhaps lower than, those measured in 1989. The correlation of NOy with N2O changes over the course of the mission. Relative to the correlation for the whole season, low values of NOy occur in February, most notably on the 22nd. The reason for the low NOy is unknown. It is generally too warm at DC-8 altitudes for the presence of PSC particles, but denitrification at higher altitudes, followed by descent, might account for the low values seen on 22 February. However, this may be unlikely since the NASA ER-2, flying during the same period, saw no evidence of denitrification at higher altitudes [Loewenstein et al., 1993>. ¿ American Geophysical Union 1993
