最近的卫星数据分析在北极海洋提供了与表面精力预算相关的改进数据集合。在这份报纸,在从表面放射预算(SRB3.0 ) 和国际卫星获得的北极海洋的表面放射性质在 19842007 期间遮蔽气候学工程(ISCCP-FD ) 被分析并且比较。我们的分析建议这些数据集在盆宽的平均季节的周期和表面反照率的空间分发显示出令人鼓舞的同意;捕捞表面短波和从所有方向的放射的流动;并且短波, longwave,和从所有方向的云放射的 forcings。然而,系统的大差异为在在大小 of23 W m2 的二个数据集合之间的放射的流动,它是首先在表面温度归因于重要差别的网络表面 longwave 被检测,特别地从 4 月到 6 月。而且,在表面短波的最大的差别和在二个数据之间的放射的 forcings 设置的从所有方向的云在在 30 W m 2 的大小的早 6 月是明显的。
Recent satellite data analysis has provided improved data sets relevant to the surface energy budget in the Arctic Ocean. In this paper, surface radiation properties in the Arctic Ocean obtained from the Surface Radiation Budget(SRB3.0) and the International Satellite Cloud Climatology Project(ISCCP-FD) during 1984– 2007 are analyzed and compared. Our analysis suggests that these datasets show encouraging agreement in basin-wide averaged seasonal cycle and spatial distribution of surface albedo; net surface shortwave and all-wave radiative fluxes; and shortwave, longwave, and all-wave cloud radiative forcings. However, a systematic large discrepancy is detected for the net surface longwave radiative flux between the two data sets at a magnitude of ~ 23 W m–2, which is primarily attributed to significant differences in surface temperature, particularly from April to June. Moreover, the largest difference in surface shortwave and all-wave cloud radiative forcings between the two data sets is apparent in early June at a magnitude of 30 W m–2.
