项目摘要

The Improved Limb Atmospheric Spectrometer (ILAS) captured many Polar Stratospheric Cloud (PSC) events in the Northern Hemisphere during the winter and early spring of 1997. The ILAS aerosol extinction coefficient and nitric acid data were compared with the theoretically predicted values for supercooled ternary solution (STS), nitric acid dihydrate (NAD) and nitric acid trihydrate (NAT) particles at equilibrium to infer the chemical composition of the observed PSC particles. The observations showed that in 1997, nitric acid-containing solid and liquid PSCs formed over the Arctic during winter and early spring, until mid-March. Some typical STS PSCs were found in mid-January, though some of the events seemed to involve ice particles. Most of the PSCs observed late in the PSC season had features of nitric acid-containing hydrates. An intensive analysis of the temperature histories suggested that most of the STS particles observed in January had experienced the thermal conditions necessary for the formation of liquid particles.
1997年冬季和早春,改进的临边大气光谱仪(ILAS)在北方半球捕获了许多极区平流层云(PSC)事件。ILAS气溶胶消光系数和硝酸的数据进行了比较,与理论预测值的过冷三元溶液(STS),硝酸二水合物(NAD)和硝酸三水合物(NAT)粒子在平衡推断所观察到的PSC粒子的化学组成。观测表明,1997年,含硝酸的固体和液体PSC在冬季和早春形成于北极上空,直到3月中旬。一些典型的STS PSC在1月中旬被发现,尽管其中一些事件似乎涉及冰粒。在PSC季节后期观察到的大多数PSC具有含硝酸水合物的特征。对温度历史的深入分析表明,1月份观测到的大多数STS粒子都经历了形成液体粒子所必需的热条件。
