Spatio-temporal variations of NOy species in the northern latitudes stratosphere measured with the balloon-borne MIPAS instrument
This paper presents the spatio-temporal distribution of NOy 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 ClONO2, and the t...
