Abstract
INTEREST in the effects on atmospheric ozone of man-made chlorine compounds has prompted research into their stratospheric chemistry. As HCl is expected to be the major temporary sink for free chlorine in the stratosphere1–4, measurements of its vertical mixing ratio profile could yield useful information as to the major source of chlorine and its future effects on ozone concentrations. We have used a balloon-borne pressure modulator radiometer (PMR) to measure the atmospheric absorption of solar infrared radiation at sunset, and we report here a vertical mixing ratio profile for gaseous HCl for the altitude range 16–39 km.
