Collaborative Research: IPY: Arctic System Reanalysis

该项目将开发北极系统再分析(ASR)。ASR可以被视为模拟和观测的混合体，它将提供北极大气-海冰-陆地表面系统在空间(20公里)和时间(3小时)的高分辨率描述。ASR将接收历史数据流以及作为IPY的一部分而开发的北极观测网络的物理组成部分的测量。来自ASR的网格场，如温度、辐射和风，也将成为冰-海洋、陆地表面和其他模式耦合的驱动因素，并将为协调模式间的比较工作提供一个焦点。ASR将允许重建北极系统的状态，从而成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，塑造国际空间站的传统观测网络。这里概述的第一代ASR将跨越2000-2010年。

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.
