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再分析（ASR）。ASR可以看作是模拟和观测的结合，它将在空间（20公里）和时间（3小时）上提供北极大气-海洋-冰-陆表面系统的高分辨率描述。ASR将吸收历史数据流以及作为国际极地年的一部分正在开发的北极观测网络物理组成部分的测量数据。来自ASR的网格场，如温度、辐射和风，也将作为耦合冰-海洋、陆地表面和其他模式的驱动因素，并将为协调模式的相互比较工作提供焦点。ASR将允许重建北极系统的状态，从而作为评估北极气候变率和监测北极变化的最先进的综合工具。ASR还将通过提供观测系统灵敏度研究的工具来塑造IPY的传统观测网络。这里概述的第一代ASR将跨越2000-2010年。
