ABSTRACT OPP-9702004 OPP-9701840 STAMNES, KNUT LUBIN, DAN UNIVERSITY OF ALASKA UNIVERSITY OF CALIFORNIA SAN DIEGO OPP-9703565 BORYS, RANDOLPH UNIVERSITY OF NEVADA This research project is a key component of a large, coordinated, multi-investigator program, Surface Heat Budget of the Arctic (SHEBA) Ocean. The research program will be conducted for 14 months from a ship frozen into the ice pack. These investigators will measure near-surface atmospheric conditions of the region from the cloud base to the surface of the permanent ice cap of the Arctic Ocean using an instumented research balloon during a period from Spring to Fall. The research will be conducted in conjunction with a DOE Atmospheric Radiation Measurement research program jointly conducted at the site. These researchers will determine the vertical profile of temperature and humidity as a function of changing cloud conditions. Their results will help determine how atmospheric heating is coupled to adsorption of heat by the ice. These measurements are critical to understanding how heat is reflected or absorbed by the ice as it melts in the summer and thickens in the winter in response to seasonal variations in climate, especially changing cloud conditions. The balloon measurement program makes an essential contribution to the SHEBA team of researchers who will measure atmospheric variables with a large array of instruments on the ice floe and aircraft flying above, as well as ice and ocean property measurements made on and below the ice floe. The combined set of measurements in SHEBA will allow refinement of climate models for the Arctic region. Those improved models will lead to better predictions of the climate and the permanence of the Arctic ice cap under a proposed global warming that could occur if atmospheric carbon dioxide levels are increased above present levels.

摘要OPP-9702004 OPP-9701840 STAMNES，KNUT LUBIN，丹·阿拉斯加大学加州大学圣地亚哥大学圣地亚哥分校OPP-9703565 BORYS，内华达州兰道夫大学这项研究项目是大型，协调的，多收益计划的大型，多功能计划，表面供热预算的重要组成部分。 该研究计划将从冻结进入冰袋的船上进行14个月。这些研究人员将在春季从春季到秋季的时期使用Inted Interned Research Balloon测量从云底座到北极海洋永久冰盖表面的近表面大气条件。 该研究将与在现场共同开展的DOE大气辐射测量研究计划一起进行。这些研究人员将确定温度和湿度的垂直轮廓，这是变化的云条件的函数。他们的结果将有助于确定如何将大气加热与冰的吸附。这些测量对于了解冰融化并在冬季融化而在冬季融化时如何反射或吸收热量对季节性变化的气候变化，尤其是改变云状况的趋势至关重要。气球测量计划为Sheba研究人员做出了重要的贡献，这些研究人员将在冰上浮动和飞机上使用大量仪器以及在冰上浮动和下方进行的冰和海洋房地产测量结果进行衡量大气变量。 Sheba中的一组测量值将允许改进北极区域的气候模型。这些改进的模型将在拟议的全球变暖下更好地预测气候和北极冰盖的永久性，如果大气中的二氧化碳水平提高到当前水平以上，可能会发生。
