29. x samples that show an average increase relative to the background of at least 0.1 ppbv. The background level during a plume event was simply obtained by linear interpolation between the concentrations adjacent to the plume (Fig. 1). Given the (true air) speed of the aircraft of 250 m/s, four samples correspond to a flight leg of 120 km. A difference of 0.1 ppbv is well above the noise of the measurement (11) and represents a significant increase above background levels of typically 70 to 200 pptv (Table 1).
30. Using a higher PV value of 4 PVU for the tropopause definition, the fraction of samples obtained within plumes is 10.4% and 1.6% for the tropospheric and stratospheric samples, respectively. Thus, the probability to observe a large-scale plume rapidly decreases in the stratosphere.

We thank Swissair for the generous support and ECO Physics Inc. for the design of the instrumentation and the assistance during the measurements. We also acknowledge H. Wernli and M. Bourqui for the trajectory calculations and R. Luethi for providing data from his archive of satellite images, which were both of great help for the interpretation of the measurements.
