Abstract
On March 17, 1976, the atmospheric absorption of solar infrared radiation at sunset was measured by a balloon-borne pressure modulator, whose major feature was a cell containing gaseous HCl, through which the incoming radiation passed. The side-band:wide-band ratio which is related to the amount of atmospheric HCl in the path between the instrument and the sun, was also measured. The vertical mixing ratio profile for gaseous HCl for the altitude range 16-39 km, was derived from the data by using a computer model. The shape of the profile implies that the major source of HCl in the stratosphere is around 32 km. The importance of this profile in determining the effects of man-made chlorine compounds on atmospheric ozone is stressed.
