9321547 Key This three-year program will quantify the individual energy streams that make up the arctic surface radiation budget, and will relate the observed radiation distribution to synoptic-scale wind, pressure, and moisture patterns. It will be the first effort to produce a comprehensive radiation climatology for the Arctic. The arctic surface energy budget, particularly that of the Arctic Ocean, has been identified as a major component of the global climate system that is potentially sensitive to climate-scale perturbations due to feedback mechanisms involving the surface albedo, the stability of the lower troposphere, and water vapor transport. The project includes four main tasks: (1) The analysis of solar and long-wave radiation data obtained directly at manned observing sites in the arctic. (2) The calculation of radiative fluxes at the surface and at the top of the atmosphere using a satellite-based cloud data product from the International Satellite Cloud Climatology Project (ISCCP). (3) For selected months, the ISCCP-derived fluxes will be compared to the corresponding synoptic regime, and (4) a study to assess the effects of the sampling and analysis procedure on the radiation statistics and their temporal variability will be undertaken. ***

这个为期三年的计划将量化构成北极表面辐射预算的各个能量流，并将观测到的辐射分布与天气尺度的风，压力和湿度模式联系起来。 这将是第一次为北极制作全面的辐射气候学。 北极表面能量收支，特别是北冰洋的表面能量收支，已被确定为全球气候系统的一个主要组成部分，由于涉及表面扰动、对流层低层稳定性和水汽输送的反馈机制，对气候尺度扰动可能敏感。 该项目包括四项主要任务：（1）分析在北极载人观测站直接获得的太阳和长波辐射数据。 (2)利用国际卫星云气候学项目的卫星云数据产品计算地面和大气层顶部的辐射通量。 (3)对于选定的月份，将把ISCCP导出的通量与相应的天气状况进行比较;（4）将进行一项研究，评估取样和分析程序对辐射统计及其时间变化的影响。 ***
