Abstract

Atmospheric absorption spectra obtained by means of balloon-borne BOMEM interferometers have been analyzed for trends in stratospheric gases. The interferograms were recorded, using the sun as the light source, on stratospheric balloon flights conducted by the Atmospheric Environment Service from 1976 to 1985. In this presentation the altitude distributions of hydrochloric acid derived from the near-infrared fundamental vibration-rotation band are reported. The R(1), R(2), and R(3) spectral lines of H35C1 at 2925.90 cm-1, 2944.91 cm-1, and 2963.29 cm-1, respectively, were used in the analysis. The results and the evidence for an increase in stratospheric HC1 are discussed in relation to other reported measurements and with respect to model calculations of stratospheric ozone depletion.
