This paper reports balloon borne measurements on two days in January 1990, from Sweden, of stratospheric densities of reactive nitrogen, nitrate aerosols, and ozone. On one days the measurements were inside the polar vortex, and on the second outside. Reactive nitrogen levels were depressed inside the vortex, which is interpreted in terms of the cold temperatures during December and early January which other measurements support. Denitrification is observed inside the vortex, relative to typical number densities observed when outside the vortex.
