This proposal aims at performing measurements by the university groups involved in the campaign PGS (POLSTRACC/ GWLCYCLE/ SALSA) planned with the HALO aircraft for winter 2015/2016. The universities involved are those of Frankfurt, Mainz, Heidelberg and Wuppertal. The University of Mainz is not a full partner of the proposal as there is no current project from the last phase of the priority programme. Rather the financial part of Mainz will be administrated via University of Frankfurt. The scientific contribution of the University Mainz is nevertheless outlined in a similar way as for the other Universities. PGS intends to provide observations of a wide range of tracers with different live times (ranging from reactive chemicals to inert tracers) to investigate chemical and dynamical aspects of the UTLS (POLSTRACC and SALSA) and the formation and propagation of gravity waves (GW-LCYCLE). The Universities of Frankfurt and Wuppertal will provide GC measurements of tracers with different lifetimes and CO2 data (Wuppertal). University Mainz will operate a laser spectrometer for fast measurements of N2O, CH4 and CO and University Heidelberg will perform measurements of reactive chlorine and bromine species using the DOAS technique. The scientific studies to be performed are outlined below and include budget studies of air mass origin, studies of chemical partitioning, studies of transport phenomena and of transport time scales. We emphasize that this proposal outlines the science to be performed with the measurements, but that the scientific studies themselves are not deliverables of this proposal due to the short funding period and limited funding for scientific staff. Instead the outcome of this proposal will be the preparation and integration of the instruments, the measurements themselves and the provision of data to the data base. We apply here for the University share of the mission costs (including certification and flight costs), for limited personnel and consumable fund and for the travel funds to carry out the measurements.

该提案旨在由参与计划于2015/2016年冬季使用HALO飞机进行的PGS（POLSTRACC/ GWLCYCLE/ SALSA）活动的大学团体进行测量。参与的大学有法兰克福、美因茨、海德堡和伍珀塔尔的大学。美因茨大学不是该提案的正式合作伙伴，因为优先计划最后阶段没有当前项目。相反，美因茨的财务部分将通过法兰克福大学管理。然而，美因茨大学的科学贡献以与其他大学类似的方式概述。PGS打算提供具有不同寿命的各种示踪剂（从反应性化学品到惰性示踪剂）的观测，以研究UTLS（POLSTRACC和SALSA）的化学和动力学方面以及重力波的形成和传播（GW-LCYCLE）。法兰克福大学和伍珀塔尔大学将提供具有不同寿命的示踪剂的气相色谱测量和CO2数据（伍珀塔尔）。美因茨大学将操作一台激光光谱仪，用于快速测量N2 O、CH 4和CO，海德堡大学将使用DOAS技术测量活性氯和溴物质。下文概述了将要进行的科学研究，其中包括气团来源的预算研究、化学分配研究、迁移现象和迁移时间尺度研究。我们强调，该提案概述了将通过测量进行的科学研究，但由于资助期短，科学工作人员的资金有限，科学研究本身并不是该提案的可交付成果。这项建议的结果将是编制和综合各项文书、测量本身和向数据库提供数据。我们在此申请大学分担的使命费用（包括认证和飞行费用）、有限的人员和消耗品基金以及进行测量的旅费。
