Analysis of Existing Aircraft Datasets of Arctic Clouds, Radiation and Surface Characteristics: Applications to SHEBA Planning

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，以明显改进对当今北极气候包括其变异性的模拟，并利用全球环流模式(GCMS)；(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，并为模型输入、模型验证和气候监测提供可靠数据。科罗拉多大学的研究人员将使用与Sheba类似的以往实验中从飞机上获取的数据来分析状态云数据，以便Sheba野外实验可能更有效率地进行规划。来自飞机的数据将用于验证从卫星获取的遥感数据的结果，以便这些结果可以扩展到拟议的实地试验的特定区域之外。?？

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 interpre- tation 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. Researchers at the University of Colorado will use data taken from aircraft in previous experiments similar to SHEBA to analyze the status cloud data so that the SHEBA field experiment may be planned more efficiently. The aircraft-derived data will be used to validate the results from remote sensing data taken from satellites so that those results may be extended beyond the specific region of the proposed field experiment. ??
