The upper troposphere-lower stratosphere (UTLS) region of the atmosphere is critically important in determining global radiative balance, which in turn influences the Earth's climate. This Small Grant for Exploratory Research (SGER) involves highly collaborative interdisciplinary research bringing together scientists and engineers from university, government and the commercial sector using aircraft measurements of water vapor, aerosol water, carbon dioxide, ozone and particle size, number and volume distribution to study processes in the UTLS region. Specific issues of interest to the investigators include: (1) the role(s) of trace species on ice particles in the UTLS; (2) factors influencing new particle nucleation, growth and loss; (3) the role of halogen chemical cycling in determining middle atmosphere ozone loss; (4) factors influencing dynamics and mixing of the UTLS; and (5) impact of airborne vehicle emissions on the chemistry, microphysics and radiative balance of the UTLS. Measurements will be made inside and outside of the rocket exhaust plumes of a number of launch vehicles, including Atlas IV and Delta rockets and the Space Shuttle launched from Kennedy Space Center at Cape Canaveral, Florida. Results from this study will be extremely useful in constraining large-scale chemical transport models and additionally improve our present understanding of the middle atmosphere water budget, heterogeneous ozone loss, and new particle formation. This high-risk high-reward SGER also has a variety of broader impacts associated with it. Those include providing a fundamental test bed for using precise fast-response in situ instruments from high-flying aircraft to make research-grade measurements in the UTLS region, and graduate student involvement as part of his/her dissertation research.

大气的对流层上层-平流层下层（UTLS）区域对于确定全球辐射平衡至关重要，而全球辐射平衡反过来又影响地球气候。这项探索性研究小额赠款（SGER）涉及高度协作的跨学科研究，汇集了来自大学，政府和商业部门的科学家和工程师，使用飞机测量水蒸气，气溶胶水，二氧化碳，臭氧和颗粒大小，数量和体积分布来研究UTLS地区的过程。研究人员感兴趣的具体问题包括：(1)微量物种在UTLS中对冰颗粒的作用；(2)影响新颗粒成核、生长和损失的因素；(3)卤素化学循环在测定中大气臭氧损失中的作用；(4)影响UTLS动力学和混合的因素；(5)机动车排放对UTLS化学、微物理和辐射平衡的影响。将对包括阿特拉斯4号和德尔塔号火箭以及从佛罗里达州卡纳维拉尔角肯尼迪航天中心发射的航天飞机在内的许多运载火箭的火箭排气羽流进行内部和外部测量。这项研究的结果将对约束大尺度化学输运模型非常有用，并进一步提高我们目前对中层大气水收支、非均质臭氧损失和新颗粒形成的理解。这种高风险、高回报的SGER还具有与之相关的各种更广泛的影响。其中包括提供一个基本的测试平台，使用高空飞行飞机上的精确快速响应原位仪器在UTLS区域进行研究级测量，以及研究生参与他/她的论文研究。
