NSCAT/NCEP Blended Ocean Winds (Version 1.0)

Ocean surface wind vector components and wind stress curl data products are derived from spatial blending of high-resolution satellite data (NASA Scatterometer - NSCAT) and global weather center reanalyses (NCEP), resulting in high temporal and spatial resolution datasets (6-hourly, and 0.5 degree). This global dataset spans 12 months, August 1996 through July 1997.

The NSCAT scatterometer data is oriented along polar-orbit satellite swaths. The double-sided instrument yielded two swaths. Each of them about 600 kilometers wide with a 350 km nadir gap and at 50 km resolution. The NCEP data consists of global, 6-hourly reanalysis fields on T62 Gaussian grid with approximate resolution of 1.8 degrees.

本数据集通过空间融合高分辨率卫星数据（美国宇航局散射计 - NSCAT）与全球气象中心再分析数据（NCEP），生成了具有高时间分辨率和空间分辨率的数据集（每6小时一次，分辨率为0.5度）。该全球数据集涵盖12个月，自1996年8月至1997年7月。NSCAT散射计数据沿极地轨道卫星条带方向排列。该双面仪器产生了两个条带，每个条带宽约600公里，赤道下方间隙350公里，分辨率为50公里。NCEP数据包括全球范围，每6小时的再分析场，基于T62高斯网格，近似分辨率为1.8度。
