The authors report vertical profile measurements of ClONO[sub 2] and HNO[sub 3] made using infrared limb emission spectra taken from a balloon borne instrument on 13 January and March 14/15, 1992. Very low ClONO[sub 2] densities were observed in January, while high numbers were seen in March. The authors interpret this as indicative of conversion of the molecule in January, while in March it indicates that most reactive chlorine is stored in this molecular form. The HNO[sub 3] measurements show no features which would indicate dramatic removal reactions such as on stratospheric clouds.
