9504158鲁宾 这项资助支持的研究是在北极系统科学（ARCSS）全球变化研究计划的主持下进行的，由海洋科学部和极地计划办公室联合赞助。 即将开展的工作是一个名为SHEBA的五年期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、测试和实施北冰洋-大气-冰过程模型，这些模型可明显改进对当今北极气候的模拟，包括利用大气环流模型模拟其变化，以及（2）提高北极卫星遥感数据的解译水平，为北极气候系统分析和模式化提供可靠数据投入、模型验证和气候监测。 这项工作涉及开发在北冰洋表面测量太阳红外线通量的新技术。 还将努力开发一种全季节算法，以便从卫星SSM/I 85.5 Ghz图像中检索海冰总浓度和多年浓度，并利用与地面全天摄影和海冰覆盖日志相匹配的高级甚高分辨率辐射计数据，验证极地云探测原则。 本提案侧重于SHEBA第一阶段技术开发和现有数据集分析。

9504158 Lubin 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 work involves development of new technology for solar infrared flux measurements at the Arctic Ocean surface. Efforts will also be made to develop an all season algorithm to retrieve total and multi-year sea ice concentrations from SSM/I 85.5 Ghz imagery from satellites and conduct a validation of polar cloud detection principles, using AVHRR data matched with surface all-sky photography and sea ice coverage logs. This proposal focuses on SHEBA PHASE I technological development and analysis of existing data sets.
