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，我们在理解云中冰的形成和演变及其对天气和气候的相关影响所必需的过程方面取得了进展，但仍然存在严重差距。其中许多可以追溯到目前穿透云层的研究飞机上使用的测量技术的不确定性和局限性。同样，由于缺乏足够的仪器来准确确定冰形成的主要模式、区分液态水和冰以及更全面地解决云颗粒和水流星的化学问题，对气溶胶(包括自然和人为的)与云粒之间复杂相互作用的描述也受到了阻碍。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的议题包括：对这些差距进行清晰和全面的描述，确定适用于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。这一地点和时机将有助于仪器制造商、飞机设施管理人员以及广泛的经验丰富和职业生涯早期的云微物理研究人员的参与，这些研究人员已经聚集在定于下周在附近的俄勒冈州波特兰举行的第13届云物理会议上。将提供支持，以支付讲习班参与者的旅费和住宿费/每日费用，并将得到另外两个联邦研究机构(美国宇航局和能源部)的类似捐款，以促进被视为促进快速进展的广泛参与。这次讲习班的智力价值在于其对促进知识进步的贡献：现有冰云测量的质量和局限性，确定进展的关键障碍和克服这些障碍的候选技术，以及制定改善合作和沟通的计划(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，通过为职业生涯早期讲习班参与者和访问讲习班出版物的学生提供教育机会，以及通过促进包括代表不足群体成员在内的不同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.
