Spatiotemporal variations of NO y species in the northern latitudes stratosphere measured with the balloon-borne MIPAS instrument
International audience This paper presents the spatiotemporal 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, temperature variations and the distribution of ClONO 2 and...
