Spatio-temporal variations of NO y species in the northern latitudes stratosphere measured with the balloon-borne MIPAS instrument
This paper presents the spatio-temporal distribution of NO y species at altitudes between 14 and 31 km as measured with the MIPAS-B instrument on the morning of 21 March 2003 in northern Scandinavia. At lower altitudes (below about 22 km), temperature variations, the distribution of ClONO 2 , and th...

This paper presents the spatio-temporal distribution of NO y species at altitudes between 14 and 31 km as measured with the MIPAS-B instrument on the morning of 21 March 2003 in northern Scandinavia. At lower altitudes (below about 22 km), temperature variations, the distribution of ClONO 2 , and the tracer N 2 O reveal the dynamics through the edge of the late arctic polar vortex. At higher altitudes, continuous measurement before, during, and after sunrise provides information about photochemistry illustrating the evolution of the photochemically active gases NO 2 and N 2 O 5 around sunrise. The measured temporal evolution of NO 2 and N 2 O 5 is compared to box modelling that is run along backward calculated trajectories. While the comparison of measured and modelled N 2 O 5 reveals significant differences, there is a good agreement between the model and observations for NO 2 in terms of volume mixing ratios but the simulated decrease shortly after sunrise is underestimated compared to the measurements.
