Plate 3. Distribution of the nitrous oxide (N20) mixing ratio (ppbv) on the 10 hPa pressure level or approximately 30 km altitude as measured on November 6, 1994 by the CRISTA instrument on board the Space Shuttle. The data were interpolated by a Kalman filter. N20 can be regarded as a tracer of dynamical motions for example a tongue of Arctic air extrudes from the North polar vortex across the United States towards the Pacific Ocean. At the same time a "streamer" ofN20 rich air extends from the tropics across eastern Asia towards the Aleutian Islands and the west cost of Canada and the United States. Another "streamer" propagates along the eastern cost of the North America towards Europe. From Offermann et al J. Geophys. Res., 104, 16311, 1999.
