Ice Sheet Models for the 21st Century: Summer School

这个奖项是为了支持一个冰盖建模暑期学校，该学校既需要改进模型中的物理特性，也需要训练有素的科学家能够进行这些改进。暑期学校将于2009年8月在波特兰州立大学举行。为期两周的暑期学校将涵盖冰盖模型的理论基础、代码开发、模型初始化和性能数据、假设检验、模型敏感性、稳定性和参数估计、社区冰盖模型（CISM）、社区气候系统模型（CCSM）等主题。学校的设计是一个协作，解决问题的框架。与会者具有不同的经验水平，从担任讲师角色的资深科学家到受邀的年轻科学家，再到通过申请选择的研究生。会议邀请了来自学术机构和国家研究实验室的参与者。这个框架与社区模式发展战略保持一致，使资源尽可能广泛地提供给研究人员。这个项目的学术价值在于，观测到冰盖对海平面上升的贡献在过去十年中从轻微的负向正转变，并在不断增长。与此同时，在格陵兰岛和一些南极地区观测到冰流量的迅速变化。这些趋势将持续多长时间或以何种程度继续是未知的。目前用于对未来进行预测的气候系统模式并不是为了处理与目前观测到的冰的快速波动有关的物理过程而设计的。因此，最近人们对在气候系统模式中改进冰盖动力学的表示非常感兴趣。这项活动的广泛影响不仅包括下一代极地研究人员的教育和培训，而且还包括与社会重要主题的相关性。2008年在俄罗斯圣彼得堡举行的南极研究科学委员会和国际北极科学委员会联合会议期间，举办了一个冰盖模型研讨会，随后举办了暑期学校。我们预计，这一计划也将在未来几年引发其他类似事件。在一个由高级和初级研究人员组成的机构间小组之间进行工作互动的机会是罕见的，我们预计这将导致未来的研究合作。课堂讲稿和练习将被收集成暑期学校的文件，并分发给参与者以及更广泛的冰川学和气候模型社区。这些和其他资源也将在蒙大拿大学维护的网站上提供。讲师、其他受邀参与者和学生申请者是国际性的。大约30%的受邀者和20%的学生申请者是女性。

This award is for support of an ice sheet modeling summer school that responds to the need for both improved physics in the models and well trained scientists able to make those improvements. The summer school will be held at Portland State University in August 2009. The list of topics to be covered during the two-week summer school include the theoretical basis of ice sheet models, code development, data for model initialization and performance, hypothesis testing, model sensitivity, stability, and parameter estimation, the community ice sheet model (CISM), the community climate system model (CCSM). The school is designed with a collaborative, problem solving framework. Participants span a range of experience levels, from senior scientists in lecturer roles, to invited young scientists, to graduate students selected by application. Participants have been invited from both academic institutions and national research labs. This framework is in keeping with a community model development strategy that makes resources available to the widest possible range of researchers.The intellectual merit of this project is that ice sheet contribution to sea level rise is observed to have transitioned from slightly negative to positive and growing over the last decade. At the same time, rapid changes in ice discharge have been observed in Greenland and in some Antarctic regions. How long or at what magnitude these trends will continue is unknown. The climate system models now in use to make future projections were not designed to address the physical processes associated with rapid fluctuations in ice such as those now observed. Thus, there is considerable recent interest in improving the representation of ice sheet dynamics in climate system models.The broader impacts of this activity include not only the education and training of the next generation of polar researchers but also the relevance to a topic of importance to society. The summer school follows from an ice sheet modeling workshop held during the 2008 Scientific Committee on Antarctic Research and International Arctic Science Committee joint meeting in St. Petersburg, Russia. We anticipate that this program too will lead to other, similar events in the years ahead. The opportunity for working interaction among an inter-institutional group of senior and junior researchers is rare and we anticipate that it will lead to future research collaborations. Lecture notes and exercises will be collected into a summer school document and distributed to participants as well as the wider glaciological and climate modeling community. This, and other resources, will also be available at a website maintained at the University of Montana. The group of lecturers, other invited participants, and student applicants is international. About 30% of the invitees and 20% of student applicants are women.
