This project will develop an Arctic System Reanalysis (ASR). The ASR, which can be viewed as a blend of modeling and observations, will provide a high resolution description in space (20 km) and time (3 h) of the atmosphere-sea ice-land surface system of the Arctic. The ASR will ingest historical data streams along with measurements of the physical components of the Arctic Observing Network being developed as part of the IPY. Gridded fields from the ASR, such as temperature, radiation and winds, will also serve as drivers for coupled ice-ocean, land surface and other models, and will offer a focal point for coordinated model inter-comparison efforts. The ASR will permit reconstructions of the Arctic system's state, thereby serving as a state-of-the-art synthesis tool for assessing Arctic climate variability and monitoring Arctic change. The ASR will also shape the legacy observing network of the IPY by providing a vehicle for observing system sensitivity studies. The first generation ASR as outlined here will span the years 2000-2010.

该项目将开发北极系统重新分析（ASR）。可以将ASR视为建模和观测的混合物，将在空间（20 km）和北极大气海冰领域的时间（3 h）中提供高分辨率描述。 ASR将摄入历史数据流以及作为IPY一部分开发的北极观察网络的物理组件的测量。来自ASR的网格场（例如温度，辐射和风）也将充当耦合冰山，陆地表面和其他模型的驱动因素，并将为协调模型间比较工作提供焦点。 ASR将允许对北极系统状态进行重建，从而用作评估北极气候变异性和监测北极变化的最新合成工具。 ASR还将通过提供观察系统敏感性研究的车辆来塑造IPY的传统观察网络。这里概述的第一代ASR将跨越2000-2010年。
