The Solar and Terrestrial Radiation Environment of the Arctic: A Study of the Albedo Feedback in the Context of Global Change

该奖项是北极系统科学计划的一部分，该计划是美国的全球变化计划。该研究项目将强调辐射收支的空间和季节变化，以及地表反射率(反照率)和云量在调节低层大气中的太阳和地面辐射方面的作用。行星反照率和亮度温度数据将从AVHRR卫星测量中获得。使用合成孔径雷达获得的其他卫星测量将提供地表类型识别和反照率。数据条目将使用理论和实地研究结果得出。这些数据将用于建模工作，以评估低层大气中的辐照度和加热率。阿拉斯加州巴罗现有的辐射测量计划将为这项研究的理论和模型方面提供验证。

This award is part of the Arctic System Science (ARCSS) Program, a U.S. Global Change Program. This research project will emphasize spatial and seasonal variability in the radiation budget and the roles of surface reflectivity (albedo) and cloud cover in regulating solar and terrestrial radiation in the lower atmosphere. Planetary albedo and brightness temperature data will be obtained from AVHRR satellite measurements. Other satellite measurements, obtained using Synthetic Aperture Radar, will provide surface type identification and albedos. Data entries will be derived using theoretical and field research results. These data will be used in modeling efforts to evaluate irradiance and heating rates in the lower atmosphere. Existing radiation measurement programs at Barrow, Alaska, will provide validation for theoretical and modeling aspects of the study.
