This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The Petascale Arctic-Atlantic-Antarctic Virtual Experiment (PAVE) will be a kilometer resolution, planetary scale ocean and sea ice simulation that will first be configured to span the Arctic Ocean, Atlantic Ocean, and Atlantic sector of the Southern Ocean, and by the end of the project period will generalize to a fully global simulation. Project implementation will be based on the Massachussetts Institute of Technology General Circulation Model (MITgcm), an ocean and sea-ice modeling system that contains non-hydrostatic and adjoint modeling capabilities that are applicable to kilometer scale and multi-year simulations. Scientific questions motivating the simulations are intended to inform sampling strategies for current and future ocean observing networks. This is a significant broader impact. The large volumes of model output will be managed and made available to researchers without petascale resources, using a novel replay capability that will be developed as part of this project.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。Petascale北极-大西洋-南极虚拟实验（PAVE）将是一公里分辨率的行星尺度海洋和海冰模拟，首先将被配置为跨越北冰洋、大西洋和南大洋的大西洋部分，到项目结束时将推广到一个完整的全球模拟。项目实施将基于麻省理工学院的环流模型（MITgcm），这是一个海洋和海冰建模系统，包含非流体静力学和伴随建模能力，适用于公里尺度和多年模拟。激发模拟的科学问题旨在为当前和未来的海洋观测网络提供采样策略。这是一个重大的更广泛的影响。大量的模型输出将被管理，并提供给研究人员，没有千万亿级资源，使用一种新的重放能力，将作为该项目的一部分开发。
