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TALO作为新HALO飞机的首批科学任务之一，优先执行。在最初的计划中，TUNK定于2009年秋季举行。使命已经提出，并由申请人协调。TDESS使命任务将包括上普法芬霍芬和佛得角群岛之间的三个断面，以测量各种各样的痕量气体。科学目的是调查在夏季和秋季之间观测到的最低平流层成分的强烈变化（例如Engel等人，2006年）。在此，我申请协助协调这场运动，并为参与该运动的大学机构提供额外的飞行和使命认证费用。在与参与TDESS的科学伙伴达成协议后，我进一步申请延长TDESS活动，以涵盖UTLS地区痕量气体观测的整个年度周期。这一扩展将被称为SALSA（使用HALO飞机在最低平流层的空气质量运输和起源的季节性）。SALSA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，只有在整个年度周期的观测可用的情况下，才能理解驱动过程。检测UTLS中成分、气团来源和传输路径可能的长期变化的先决条件是彻底量化这个大的季节性周期。这是SALSA的主要目标之一。协调活动将包括活动的后勤组织和准备、有效载荷的组织以及德国航天中心、仪器小组和支持小组之间的通信。数据集的质量控制和参与TSCHE/SALSA的团体之间的科学研究的协调也是这项建议的一部分。因此，本提案的主要目的是提供调查夏季和秋季之间进入平流层最低层的空气质量输送的科学问题所需的高质量数据集，并在项目扩展的框架内，提供UTLS中痕量分布的年度周期，以便提供更完整的图片，这将允许调查的季节影响UTLS和基本过程相结合的观测与模式研究。
