At the measurement campaign 1998 N2O measurements inside
and outside the polar vortex were performend. Both in the spectra and in the
retrieved vmr profiles the sinking of N2O inside the polar
vortex is visible.

N2O measurements outside (6 February) and inside (23 February)
the polar vortex. The upper graph shows the measured spectra and the lower graph
the retrieved profiles. The sinking airmasses inside the polar vortex lead to a sinking
of N2O.
