Measurements of the Microstructures and Radiative Properties of Stratiform Clouds and Aerosols, and the Spectral Albedos of Ice Surfaces at SHEBA

HOBBS, PETER UNIVERSITY OF WASHINGTON， PI提议开展一项空中测量计划，旨在研究云对热吸附和辐射的作用，并测量北冰洋浮冰的光谱反射率。云的性质和冰表面辐射的反射率都影响气候反馈机制。该实地项目将与波弗特海的北极海洋表面热收支（SHEBA）项目一起进行。机载测量将与谢巴站在冰上的测量相结合，以检查海洋-大气-冰系统对气候的影响。SHEBA的结果将用于改进用于预测气候对变化的环境条件的响应的全球环流模型。

ABSTRACT OPP-980816 HOBBS, PETER UNIVERSITY OF WASHINGTON The PI proposes to conduct an airborne measurement program designed to examine the role of clouds on heat adsorption and radiation, and to measure the spectral reflectivity of ice floes in the Arctic Ocean. Clouds properties and reflectance of radiation from the ice surface both influence climate feedback mechanisms. The field program will be conducted in conjunction with the Surface Heat Budget of the Arctic (SHEBA) Ocean project in the Beaufort Sea. Airborne measurements will be combined with measurements taken at the SHEBA station on the ice to examine the effects of the ocean-atmosphere-ice system on climate. The SHEBA results will be used to improve global circulation models used to predict climate response to changing environmental conditions.
