Observation of NOy uptake by particles in the arctic tropopause region at low temperatures
Measurements pf gas- and condensed-phase NOy, HNO3, O-3, and particle concentration and size were performed on 24 January 1997 during POLSTAR on a flight through an ice cloud. In the ice cloud below the tropopause only 2 to 4 pptv particle NOy were detected. The observed average mixing ratio of tota...
