The Assimilation of Data from Satellite Data Sources for Mesoscale Analyses in Support of SHEBA

这笔赠款支持的研究由北极系统科学(ARCS)全球变化研究计划赞助，并由海洋科学部和极地方案办公室联合赞助。将开展的工作是迈向一个名为SHEBA的五年重大研究项目的初步步骤，该项目旨在研究北冰洋的热量收支及其对全球变化的影响。SHEBA的主要目标是：(1)开发、测试和实施北极海洋-大气-冰过程模式，利用全球环流模式明显改进对当今北极气候包括其变异性的模拟，以及(2)改进对北极卫星遥感数据的解释，用于北极气候系统的分析，并为模型投入、模型验证和气候监测提供可靠的数据。科罗拉多大学和阿拉斯加大学研究人员的这一联合项目将增加对北极气候反馈机制的理解。将来自卫星的气象数据与区域大气模型结合起来，将能够更好地预测1997年第二阶段实地试验拟议地点的北极气候变量。这项研究将是规划研究的实验阶段所必需的。

Research supported by this grant is under the auspices of the Arctic Systems Science (ARCSS) Global Change Research Program and is jointly sponsored by the Division of Ocean Sciences and the Office of Polar Programs. Work to be performed represents preliminary steps towards a major 5-year research project named SHEBA, which is envisioned to study the heat budget of the Arctic Ocean and its impact on global change. The primary goals of SHEBA are: (1) to develop, test and implement models of arctic ocean-atmosphere-ice processes that demonstrably improve simulations of the present day arctic climate, including its variability, using General Circulation Models (GCMs), and (2) to improve the interpretation of satellite remote sensing data in the Arctic for analysis of the arctic climate system and provide reliable data for model input, model validation and climate monitoring. This joint project by researchers at the University of Colorado and University of Alaska will increase the understanding of the feedback mechanisms in Arctic climate. The integration of meteorological data derived from satellites with regional atmospheric models will allow better prediction of Arctic climate variables at the proposed site for the Phase 2 field experiment in 1997. This research will necessary for planning the experiment phase of the study.
