Abstract

In a flight through a wave cloud during SUCCESS on 2 May 1996, simultaneous forward- and aft-facing NO_y inlets were used to infer the amount of condensed-phase NO_y present on ice particles that were up to a few minutes old. Condensed-phase amounts were 25-75 pptv, or 10-20% of gas-phase NO_y. Given the rapid HNO₃ uptake on ice observed in the laboratory, a model calculation implies that virtually all of the gas-phase HNO₃ will be depleted in the first 1-2 minutes after the appearance of ice. Thus the NO_y observations are consistent with the laboratory results only if the ambient HNO₃/NO_y ratio is 10-20%.
