Workshop for In Situ Airborne Instrumentation: Addressing and Solving Measurement Problems in Ice Clouds; Seaside, Oregon; June 25-27, 2010

尽管在过去几十年中，我们对云中冰的形成和演变以及对天气和气候的相关影响所必需的过程的理解取得了进展，但仍然存在严重的差距。 其中许多可以追溯到目前在穿云研究飞机上使用的测量技术的不确定性和局限性。 描述气溶胶（自然和人为）和云粒子之间的复杂相互作用同样受到缺乏足够的仪器，以准确地确定冰的初始模式，区分液态水冰，更全面地解决云粒子和水凝物的化学。 2010年6月25日至27日在俄勒冈州海滨举行的夏季研讨会将讨论以下主题：对这些差距进行清晰而全面的描述，确定适合弥合这些差距的新兴技术，以及讨论有助于实现这些目标的标准化数据处理和交换协议。 这个地点和时间安排将有利于仪器制造商、飞机设施管理人员以及已经聚集在俄勒冈州附近的波特兰参加第13届云物理会议的经验丰富和早期职业云微物理研究人员的广泛参与。 将提供支助，支付讲习班参加者的旅费和住宿/每日生活费，另外两个联邦研究机构也将提供类似的捐助（美国航天局和美国能源部），以促进广泛的参与被视为催化迅速进展的关键。目前可用的冰云测量的质量和局限性，识别进展的关键障碍和克服这些障碍的候选技术，以及制定改进合作和沟通的计划（例如，更广泛的影响将来自通过综合技术说明和相关期刊出版物传播讲习班成果，通过为职业早期讲习班参与者和学生提供教育机会，以及促进包括代表性不足群体成员在内的各种讲习班参与者之间的交流。

Despite advancements over the past several decades in our understanding of processes essential to the formation and evolution of ice in clouds and associated impacts on weather and climate, serious gaps remain. Many of these can be traced to uncertainties and limitations of measurement technologies currently employed aboard cloud-penetrating research aircraft. Descriptions of complex interactions between aerosols (both natural and anthropogenic) and cloud particles are similarly hindered by lack of adequate instrumentation to accurately identify primary modes of ice initiation, discriminate liquid water from ice, and more comprehensively address the chemistry of cloud particles and hydrometeors. Development of a clear and comprehensive description of these gaps, identification of emerging technologies appropriate for bridging them, and discussion of standardized data processing and exchange protocols that would facilitate progress toward these objectives are among topics to be addressed at a summer workshop to be held June 25-27, 2010 at Seaside, Oregon. This location and timing will facilitate participation of instrument builders, aircraft facility managers, and a desirably broad spectrum of both seasoned and early-career cloud microphysical researchers already gathering for the 13th Conference on Cloud Physics, slated for the following week in nearby Portland, Oregon. Support will be offered to defray travel and lodging/per diem expenses of workshop participants, and will be complemented by analogous contributions from two other federal research agencies (NASA and DOE) to facilitate the broad participation viewed as critical to catalyzing rapid progress.The intellectual merit of this workshop rests in its contribution to advancement of knowledge re: the quality and limitations of currently-available ice cloud measurements, the identification of key obstacles to progress and candidate technologies to surmount these obstacles, and development of plans for improved collaboration and communication (e.g., standardized protocols for instrument calibration and data exchange) to support improved analysis and interpretation of these measurements.Broader impacts will derive from dissemination of workshop outcomes via a comprehensive Technical Note and through an associated journal publication, via educational opportunities for both early-career workshop participants and students accessing workshop publications, and by facilitating exchange across a diverse group of workshop participants including members of underrepresented groups.
