Weinheimer, A.J., Campos, T.L., Walega, J.G., Grahek, F.E., Ridley, B.A., Baumgardner, D., Twohy, C.H., Gandrud, B. and Jensen, E.J. (1998). Uptake of NO_y on wave-cloud ice particles. Geophysical Research Letters 25: doi: 10.1029/97GL02957. issn: 0094-8276.

In a flight through a wave cloud during SUCCESS on 2 May 1996, simultaneous forward- and aft-facing NOy inlets were used to infer the amount of condensed-phase NOy 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 NOy. 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 NOy observations are consistent with the laboratory results only if the ambient HNO3/NOy ratio is 10--20%. ¿ 1998 American Geophysical Union
