Stratospheric volume mixing ratio profiles of chlorine nitrate (ClONO{sub 2}) have been retrieved from 0.01-cm{sup {minus}1} resolution infrared solar occultation spectra recorded at latitudes between 14{degrees}N and 54{degrees}S by the atmospheric trace molecule spectroscopy Fourier transform spectrometer during the ATLAS 1 shuttle mission (March 24 to April 2, 1992). The results were obtained from nonlinear least squares fittings of the ClONO{sub 2} {nu}{sub 4} band Q branch at 780.21 cm{sup {minus}1} with improved spectroscopic parameters generated on the basis of recent laboratory work. The individual profiles, which have an accuracy of about {+-}20%, are compared with previous observations and model calculations. 25 refs., 3 figs., 2 tabs.
