Contributions to SHEBA from Arctic Ocean Section 1994

9504158卢宾研究项目由北极系统科学（ARCSS）全球变化研究项目资助，由海洋科学部和极地项目办公室联合主办。即将进行的工作是一项名为“示巴”的重大5年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-冰过程的模式，这些模式明显改善了使用环流模式（GCMs）对当今北极气候（包括其变率）的模拟，以及(2)改善北极卫星遥感数据的解释，以分析北极气候系统，并为模式输入、模式验证和气候监测提供可靠的数据。这项工作涉及开发在北冰洋表面测量太阳红外通量的新技术。还将努力开发一种全季节算法，从卫星的SSM/I 85.5 Ghz图像中检索总海冰浓度和多年海冰浓度，并使用AVHRR数据与地面全天摄影和海冰覆盖日志相匹配，对极地云检测原理进行验证。该提案侧重于SHEBA第一阶段的技术开发和现有数据集的分析。

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.
