Collaborative Research: Documenting, Understanding, and Predicting the Aggregate Scale Surface Radiation Flux for SHEBA

科罗拉多州朱迪斯大学OPP-9703127库里研究项目是一个大型的、协调的、多个研究人员参与的计划--北冰洋表面热量平衡计划的关键组成部分。这项研究计划将在一艘冻结在冰层中的船只上进行14个月。这些调查人员将在春季和秋季从一架经过科学测量的C-130飞机上测量北冰洋永久冰盖的大气条件，同时美国国家航空航天局(NASA)在该地点联合开展的研究项目。这些研究人员将确定随着云层条件的变化，辐射到浮冰上的热量的流量。他们的结果将有助于确定大气加热与冰吸收热量的耦合方式。这些测量对于理解冰是如何反射或吸收热量至关重要的，因为冰在夏天融化，在冬天变厚，以应对气候的季节性变化。飞机测量计划对Sheba研究团队做出了重要贡献，他们将使用浮冰和上方飞行的飞机上的大量仪器以及浮冰上和冰下的冰和海洋性质测量来测量大气变量。在舍巴的一套综合测量将允许改进北极地区的气候模型。这些改进的模型将导致更好地预测气候和北极冰盖在拟议的全球变暖下的持久性。如果大气中的二氧化碳水平增加到目前的水平，就可能发生全球变暖。

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.
