The Solar Mesosphere Explorer Satellite (SME) has measured stratospheric NO2 since January 1982 using a visible light spectrometer. The presence of large amounts of aerosol injected into the stratosphere by El Chichon on April 4, 1982, temporarily prevented NO2 data analysis. At the end of 1983 the volcanic aerosol content of the atmosphere, although present, had decreased sufficiently to again allow reliable NO2 measurements. Monthly average results at 10 mbar are presented for a full year of SME observations, from October 1983 to September 1984. The observed morphology of NO2 is discussed. Interesting features include large amounts of NO2 in the summer hemisphere, with more in the south than the north. A low usually exists in the tropics. A comparison to Nimbus 7 Limb Infrared Monitor of the Stratosphere (LIMS) observations shows similar features. ¿American Geophysical Union 1987
