9504158卢宾研究由这笔赠款资助，由北极系统科学全球变化研究计划赞助，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。这项工作涉及开发测量北冰洋表面太阳红外通量的新技术。还将努力开发一个全季算法，从卫星SSM/I 85.5 GHz图像中提取海冰总浓度和多年浓度，并利用AVHRR数据与地面全天摄影和海冰覆盖记录相匹配，对极云探测原理进行验证。该提案的重点是SHEBA第一阶段技术开发和对现有数据集的分析。

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.
