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.

小行星9504356 这项资助支持的研究是在北极系统科学（ARCSS）全球变化研究计划的主持下进行的，由海洋科学部和极地计划办公室联合赞助。 要执行的工作是一个名为SHEBA的主要5年研究项目的初步步骤：（1）开发、测试和实施北极海洋-大气-冰过程模型，这些模型可明显改进对当今北极气候的模拟，包括利用大气环流模型模拟其变化，（2）提高北极卫星遥感资料的解译能力，为北极气候系统分析提供可靠的数据，为模式输入、模式验证和气候监测提供可靠的数据。 这项工作是内华达州大学甜点研究所和阿拉斯加大学地球物理研究所之间的合作努力。 SHEBA实地项目期间的几个关键大气测量将由系留气球进行，这些气球将携带科学仪器到冰面以上一公里处。 其中一些仪器必须根据北极条件进行调整和测试。 一组测量集中于云微植物，另一组涉及辐射热通量测量。 当气球垂直穿过云层时，微物理仪器将提供不同高度云粒子的特征。 辐射仪器包将包括自动调平的向上和向下短波通量辐射计、云液态水仪器以及压力、温度、湿度和风的气象仪器包。 这项合作努力将提供共同的业务和数据记录组件。 该部也提供部分支助。的能量
