In Situ Measurements of the Upper StratosphericNegative Ion Composition and InferredSulphuric Acid Ion Thermochemistry
-
摘要: 本文报道了在法国南部(44°N)上空进行的两次气球飞行实验的部分负离子成分探测结果.利用自然负离子谱计算了某些硫酸离子的热化学常数ΔG, ΔH和ΔS.讨论了上升段测量中气球表面放气造成的离子化学污染.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.
