ABSTRACT OPP-9703127 CURRY, JUDITH UNIVERSITY OF COLORADO 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 atmospheric conditions of the permanent ice cap of the Arctic Ocean from a scientifically instrumented C-130 aircraft during the Spring and Fall in conjunction with a NASA research program jointly conducted at the site. These researchers will determine the flux of incoming heat radiating onto the ice floe 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. The aircraft 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-9703127科罗拉多州朱迪思大学库里该研究项目是大型，协调的，多启发式计划的关键组成部分，北极（Sheba）海洋的表面热预算。 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和秋季与该地点共同开展的NASA研究计划一起，在春季和秋季的科学仪器C-130飞机上测量北极海洋永久冰盖的大气条件。这些研究人员将确定传入的热量辐射到冰浮球上的通量，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。这些测量对于理解冰在夏季融化而在冬季融化并响应气候季节性变化而在冬季融化并在冬季融化时如何反射或吸收热量至关重要。飞机测量计划为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浮游在冰上和下方进行的冰和海洋房地产测量值进行测量大气变量。 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。
