Applications of Small Research Aircraft to Understanding Horizontal Inhomogeneities in Surface Fluxes for SHEBA

布鲁克斯，STEVEN MASLANIK，JAMES OCEANIC和科罗拉多大学大气管理局这个研究项目是一个大型的、协调的、多研究者计划的关键组成部分，北极海洋的表面热量收支（SHEBA）。这项研究计划将在一艘被冻成冰块的船上进行14个月。这些调查人员将利用北冰洋永久冰帽不同表面冰况的热通量测量结果。他们的结果将有助于确定大气和海洋加热如何与冰的热量吸收相结合。这些测量对于了解海冰如何反射或吸收热量至关重要，因为海冰在夏季融化，在冬季变厚，以应对气候的季节性变化。对表面冰况的测量将被纳入一个建模程序，该程序将对SHEBA研究小组的测量和建模做出重要贡献。该项目将是SHEBA大气和海洋变量完整测量方案的组成部分，该方案利用浮冰上的大量仪器和在其上方飞行的飞机以及在浮冰上和浮冰下进行的冰和海洋性质测量。SHEBA的一套综合测量和海冰模型将使北极地区的气候模型得到改进。这些改进的模型将有助于更好地预测气候以及在拟议的全球变暖情况下北极冰盖的持久性，如果大气二氧化碳水平增加到目前水平以上，可能会发生全球变暖。

ABSTRACT OPP-9701523 OPP-9701880 BROOKS, STEVEN MASLANIK, JAMES NATIONAL OCEANIC AND UNIVERSITY OF COLORADO ATMOSPHERIC ADMINISTRATION 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 utilize measurements of the flux of heat from different surface ice conditions of the permanent ice cap of the Arctic Ocean. Their results will help determine how atmospheric and oceanic heating is coupled to adsorption of heat by the ice. These measurements are critical to understanding how heat is reflected or absorbed by the sea ice as it melts in the summer and thickens in the winter in response to seasonal variations in climate. The measurements of surface ice conditions will be incorporated into a modeling program that makes an essential contribution to the measurements and modeling by the SHEBA team of researchers. This project will be integral to the full SHEBA measurement program of atmospheric and oceanic variables conducted 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 and sea ice models 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.
