9414172 Hobbs This project is an airborne study of arctic stratus clouds with the objective of obtaining several comprehensive sets of simultaneous measurements of their microstructure and spectral radiative properties. Such concurrent measurements are basic to the improvement of current models of radiative properties of stratus clouds. These models in turn are a crucial component of global circulation models which form an important basis for global change studies. The development of optimized radiative forcing algorithms is the objective of a major research effort. Additional objectives of this project are to measure the spectral reflective properties of various arctic surfaces such as tundra, open ocean, and melting and refreezing sea ice, and to test a new approach for distinguishing water clouds from snow and ice surfaces. The observations will be made from a Convair C-131A aircraft configured specifically for airborne research. ***

这个项目是对北极层云的空中研究，目的是获得几套全面的同时测量它们的微观结构和光谱辐射特性。这种同时进行的测量是改进目前的层云辐射特性模式的基础。这些模式又是全球环流模式的重要组成部分，而全球环流模式又是全球变化研究的重要基础。发展优化的辐射强迫算法是一项主要研究工作的目标。该项目的其他目标是测量各种北极表面的光谱反射特性，如苔原、开阔的海洋、融化和再冻结的海冰，并测试一种区分水云和冰雪表面的新方法。观测将由一架专门为空中研究配置的Convair C-131A飞机进行。＊＊＊
