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.

这个奖项是为了支持一个冰盖建模暑期学校，该学校响应了模型中改进物理学的需求，以及训练有素的科学家能够做出这些改进。 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的主题包括冰盖模型的理论基础，代码开发，模型初始化和性能的数据，假设检验，模型灵敏度，稳定性和参数估计，社区冰盖模型（CISM），社区气候系统模型（CCSM）。 学校的设计是一个协作，解决问题的框架。参与者跨越了一系列的经验水平，从讲师角色的高级科学家，到受邀的年轻科学家，再到通过应用程序选择的研究生。与会者来自学术机构和国家研究实验室。这一框架符合社区模式发展战略，使尽可能多的研究人员获得资源，这一项目的智力价值是，冰盖对海平面上升的贡献被观察到从轻微的负面转变为积极的，并在过去十年中不断增长。与此同时，在格陵兰岛和南极一些地区观察到冰排放的迅速变化。这些趋势将持续多久或以何种程度持续尚不清楚。目前用于预测未来的气候系统模型并不是为了处理与目前观察到的冰层快速波动有关的物理过程。因此，最近人们对改进气候系统模型中冰盖动态的表现有相当大的兴趣，这一活动的更广泛影响不仅包括对下一代极地研究人员的教育和培训，而且还包括与一个对社会具有重要意义的专题的相关性。 夏季学校是在2008年南极研究科学委员会和国际北极科学委员会在俄罗斯圣彼得堡彼得堡举行的联合会议期间举行的冰盖建模研讨会之后举办的。我们预计，这一计划也将导致其他类似的事件在未来几年。高级和初级研究人员的机构间小组之间的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到暑期学校文件，并分发给参与者以及更广泛的冰川和气候建模社区。这一点，以及其他资源，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人的团体是国际性的。大约30%的受邀者和20%的学生申请者是妇女。
