We propose to deploy our gaschromatographic system GhOST-MS (Gas chromatograph for the Observation of tracers - coupled with a mass spectrometer) on HALO during the WISE mission. GhOST-MS will measure tracers with different lifetimes (ranging from near infinite like SF6 to a few weeks (CHBr3)) in the lower and lowermost stratosphere. These measurements will be combined with observations from the TACTS, SALSA and POLSTRACC campaigns. We will focus on two scientific topics: the derivation of transit time distributions (age-spectra) and the derivation of a halogen budget of the lower and lowermost stratosphere. A focus of the halogen budget will be on bromine. The evaluation be performed for different seasons and for different meteorological situations. A new method will be developed to derive bimodal age spectra, which will lead to a better description of the transit time distributions relevant to the lower and lowermost stratosphere. A close collaboration with Forschungszentrum Jülich and the CLaMS modelling work performed there is planned. The method developed by Ehhalt et al. (2007) will be used as a basis for our new approach. With respect to the halogen budget we propose to use our measurements to derive the amount of inorganic bromine and chlorine from short-lived source gases in the lower and lowermost stratosphere, where it can react with ozone. These data will be combined with quasi-simultaneous measurements of inorganic halogen species by the University of Heidelberg, in order to derive a complete halogen, especially bromine budget.

我们建议在明智的任务期间在光晕上部署气体形态系统幽灵-MS（用于观察示踪剂的气相色谱法 - 与质谱仪相结合）。 Ghost-MS将测量具有不同寿命的示踪剂（从近乎无限的SF6到几周到几周（CHBR3））在最低和最低平流层的范围内。这些测量将与Tact，Salsa和Polstracc活动的观察结果结合使用。我们将重点介绍两个科学主题：运输时间分布的推导（年龄谱）和最低平流层下部和最低平流层的卤素预算的推导。卤素预算的重点将放在溴上。在不同的季节和不同的气象情况下进行评估。将开发一种新方法来得出双峰年龄光谱，这将使对与最低平流层相关的过境时间分布进行更好的描述。与ForschungszentrumJülich进行了密切合作，并计划在此处执行的蛤lam建模工作。 Ehhalt等人开发的方法。 （2007年）将被用作我们新方法的基础。关于卤素预算，我们建议使用我们的测量结果从最低和最低平流层中的短寿命源气体中得出无机溴和氯的量，在那里它可以与臭氧反应。这些数据将与海德堡大学对无机卤素物种进行准同时测量，以得出完整的卤素，尤其是溴预算。
