TACTS has been chosen as one of the first scientific missions for the new HALO aircraft by the scientific steering committee (German: Wissenschaftlicher Lenkungsausschuss, WLA) to be carried out with priority. In the initial planning, TACTS was scheduled for the fall of 2009. The mission has been proposed and is co-ordinated by the applicant. The TACTS mission will consist of three transects between Oberpfaffenhofen and the Cape Verde Islands to measure a wide range of trace gases. The scientific aim is to investigate the strong change in composition of the lowermost stratosphere observed between summer and fall (e.g. Engel et al., 2006). Here, I apply for assistance in the co-ordination of the campaign, and for the additional flight and mission certification costs for the University institutes involved in TACTS. In agreement with the scientific partners involved in TACTS, I further apply for an extension of the TACTS campaign, in order to cover an entire annual cycle of trace gas observations in the UTLS region. This extension will be called SALSA (Seasonality of Air mass transport and origin in the Lowermost Stratosphere using the HALO Aircraft). The scientific rationale for SALSA is that many aspects of Stratosphere-Troposphere-exchange (STE) have a strong seasonality and the driving processes can only be understood if an entire annual cycle of observations is available. A prerequisite for detecting possible long term changes in composition, air mass origin and transport pathways in the UTLS is a thorough quantification of this large seasonal cycle. This is one of the main goals of SALSA. The co-ordination activity will consist of the logistical organisation and preparation of the campaign, the organisation of the payload and the communication between DLR, the instrument teams and the support teams. Quality Control of the data set and co-ordination of scientific studies between the groups involved in TACTS/SALSA are also part of this proposal. The main aim of this proposal is thus to provide a high quality data set needed to investigate the scientific question of air mass transport into the lowermost stratosphere between summer and fall and in the frame of the extension of the project, the provision of an annual cycle of trace distributions in the UTLS, in order to provide a more complete picture, which will allow the investigation of seasonal influences on the UTLS and the underlying processes by combining the observations with model studies.

科学指导委员会（德语：Wissenschaftlicher Lenkungsausschuss，wla）选择了Tacts作为新的Halo飞机的首批科学任务之一。在最初的计划中，计划定于2009年秋季进行。已提出任务并由申请人协调。 Tacts Mission将由Oberpfaffenhofen和Cape Verde群岛之间的三个横断面组成，以测量各种痕量气体。科学的目的是研究夏季和秋季之间观察到的最低平流层组成的强烈变化（例如Engel等，2006）。在这里，我在竞选协调方面申请协助，并为参与机智的大学机构提供额外的飞行和任务认证费用。与参与机智的科学合作伙伴一致，我进一步申请了Tacts运动的扩展，以涵盖UTLS地区的整个年度痕量天然气观测周期。该延伸将称为莎莎（使用光环飞机在最低平流层中空气传输和起源的季节性）。莎莎的科学原理是平流层 - 对流层 - 交换（Ste）的许多方面具有很强的季节性，并且只有在整个观测周期都可用时才能理解驾驶过程。检测UTLS中可能长期变化，空气质量起源和运输途径的长期变化的先决条件是对这个大季节性周期的彻底量化。这是莎莎的主要目标之一。协调活动将包括集中组织和运动的准备，有效载荷的组织以及DLR，仪器团队和支持团队之间的沟通。该提案的一部分是对数据集的数据集的质量控制以及涉及战术/莎莎群体涉及的群体之间的科学研究的质量控制。因此，该提案的主要目的是提供一个高质量的数据集，以调查夏季和秋季之间的空气质量运输到最低平流层的科学问题，并在项目扩展的框架内，提供UTL中的痕量分布周期，以便提供更完整的图像，从而可以通过对UTL进行季节性的影响，以实现UTL和下层的研究。
