Limb sounding measurements of infra‐red emission at 6.2 μm from the Earth's atmosphere have been made by the Improved Stratospheric and Mesospheric Sounder (ISAMS). This provides a pressure modulated gas‐correlation signal and a wideband signal from which NO 2 and aerosol extinction at 6.2 μm are jointly retrieved between 100 mb and 0.3 mb. The retrieval scheme is discussed with reference to NO 2 and a qualitative comparison made with LIMS data. The ISAMS Northern hemisphere NO 2 data for January 9th 1992 are then examined and the importance of dynamical factors highlighted.
