This paper describes balloon borne air samples taken above Kiruna (67.9[degrees]N; 21.1[degrees]E) during EASOE, which monitored the N[sub 2]O density, as the polar vortex shifted, between altitudes of 10 and 31 km. Different air samplers were used to collect samples. The results show vertical profiles, outside, in the edge of, and inside the vertex, which reveal variation in mixing ratios as airmasses mix both vertically and horizontally near the vortex.
