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可被视为建模和观测的结合体，将提供北极大气-海冰-陆地表面系统在空间（20公里）和时间（3小时）上的高分辨率描述。北极观测站将接收历史数据流，沿着对作为国际极地年一部分正在开发的北极观测网物理组成部分的测量。来自ASR的网格场，如温度、辐射和风，也将作为耦合冰-海洋、陆地表面和其他模型的驱动因素，并将为协调的模型相互比较工作提供一个焦点。ASR将允许重建北极系统的状态，从而作为评估北极气候变异性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敏感性研究的工具来塑造IPY的传统观测网络。这里所概述的第一代ASR将跨越2000-2010年。
