This article describes the results of vertical measurements of HNO[sub 3] and HCN from a balloon borne instrument above Kiruna, Sweden on 13 February, 1992. The HCN profiles were basically constant. The HNO[sub 3] profiles showed more structure, particularly relative to 24 km altitude. The relative densities below 24 km were different on the ascent, vs descent of the balloon, which the authors interpret in terms of dissolution of nitric acid vapor in sulfuric acid aerosols present due to volcanic eruptions.
