NASA ISS_RapidScat Project

This dataset contains the ISS-RapidScat Version 2.0 Level 1B geo-located Sigma-0 measurements and antenna pulse "egg" and "slice" geometries as derived from ephemeris and the Level 1A dataset. The pulse "egg" represents the complete footprint of the pulse, which has a spatial geometry of approximately 25 km by 35 km. There are 8 slices that constitute the range-binned components of a pulse each of which has a spatial geometry of approximately 25 km by 7 km. The orientation of the long dimension of the slices varies with the rotation of the antenna and thus does not align with the along/across track orientation of the wind vector grid in...本数据集包含国际空间站快速散射计（ISS-RapidScat）2.0版1B级（Level 1B）地理定位Sigma-0（geo-located Sigma-0）测量数据，以及由星历数据与1A级（Level 1A）数据集推导得到的天线脉冲"蛋形"与"切片"几何结构。脉冲"蛋形"代表脉冲的完整覆盖足迹，其空间几何尺寸约为25千米×35千米。构成脉冲距离向分档分量的共有8个切片，每个切片的空间几何尺寸约为25千米×7千米。切片长轴的朝向随天线旋转而变化，因此无法与风矢量网格的沿轨/跨轨方向对齐……
