Deployment of Surface-Based, Active Remote Sensors During SHEBA

美国国家海洋和大气管理局OPP-9701730 Uttal，TANEIL国家海洋和大气管理局这项研究项目是一个大型的、协调的、多个调查员项目的关键组成部分，北极(SHEBA)洋面热量收支。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。这位调查员将使用一系列大型仪器来测量整个年度周期中的云属性和云底。这项研究对于确定随着大气和海洋条件的变化，云条件对辐射到浮冰上的入射热通量的影响将是重要的。他们的结果将有助于确定大气加热与海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。这一云特性测量计划对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浮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。

OPP-9701730 UTTAL, TANEIL NATIONAL OCEANIC AND 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. This investigator will use a large instrument array of instruments to measure cloud properties and cloud-base through a full annual cycle. This research will be important for the determination of the effects of cloud conditions on the flux of incoming heat radiating onto the ice floe as a function of changing atmospheric and oceanic conditions. Their results will help determine how atmospheric heating is coupled to adsorption of heat by the sea 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. This cloud properties 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.
