Abstract

Abstract

Negative ions, height profiles from 20 km to 41 km measured during the recent two balloon flights over south Prance (44°N) are published. Therrnochemical constants △G, △H and △S for some sulphuric acid cluster ions are inferred from the in situ ion composition measurements. The chemical contamination during ascent leg measurements is revealed to be caused from the ion chemical reactions involved in the reeva-poration of water vapor from balloon surfaces.
