9504356 Stamnes Research supported by this grant is under the auspices of the Arctic Systems Sciences (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 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 is a collaborative effort between the University of Nevada, Dessert Research Institute and the University of Alaska, Geophysical Institute. Several key atmospheric measurements during the SHEBA field program will be made from tethered balloons that will carry scientific instruments up to a kilometer above the ice surface. Some of these instruments must be adapted and tested for Arctic conditions. One group of measurements focus on cloud microphytsics and another group involve radiative heat fluz measurements. The microphysics instruments will provide characterizations of cloud particles at different altitudes as the balloon moves vertically through cloud layers. The radiative instrument package will consist of self-leveling up- and down- short-wave flux radiometers, cloud liquid water instruments, and meteorological packages for pressure, temperature, humidity, and wind. The collaborative effort will provide common operational and data logging components. Partial support is also being provided by Dept. of Energy.

这项赠款支持的9504356 Stamnes研究是在北极系统科学（ARCSS）全球变化研究计划的主持下，并由海洋科学部和极地计划办公室共同赞助。 要执行的工作代表着一个名为SHEBA的主要5年研究项目的初步步骤：（1）要开发，测试和实施北极海洋 - 大气 - 冰的模型，这些模型可证明改善了当今的北极气候的模拟，包括其可变性，并使用一般循环模型（GCMS）和（2）进行远程测试数据的解释。模型输入，模型验证和气候监控。 这项工作是内华达大学，甜点研究所和地球物理学院阿拉斯加大学之间的合作努力。 Sheba野外计划期间的几项重要大气测量将由束缚气球制成，这些气球将将科学仪器运送到冰层上方一公里处。 这些仪器中的一些必须适应北极条件。 一组测量集中在云微生植物上，另一组涉及辐射热fluz测量。 当气球通过云层垂直移动时，微物理仪器将在不同高度的云颗粒中提供云颗粒的特征。 辐射仪器包将包括自我升级的上下短波通量辐射仪，云液体水仪器以及用于压力，温度，湿度和风的气象包装。 协作工作将提供常见的操作和数据记录组件。 能源部也提供部分支持。
