NASA swot Project

This dataset provides a simulated water surface elevation product that resembles the Ka-band Interferometer (KaRIn) measurements by the Surface Water and Ocean Topography (SWOT) mission. SWOT will provide a global coverage but this simulated subset focuses on the North America continent. The simulated SWOT KaRIN swaths span 128 km in the cross-swath direction with a 20-km nadir gap. This product is complementary to the L2_HR_PIXC_V1 product. It provides a less noisy, height-constrained geolocation (latitude, longitude, and height) of the L2_HR_PIXC_V1 pixels. In addition, this product provides...本数据集提供一款模拟水面高程产品，其数据表现与地表水与海洋地形测绘（Surface Water and Ocean Topography, SWOT）任务搭载的Ka波段干涉仪（Ka-band Interferometer, KaRIn）实测结果高度吻合。SWOT任务可实现全球观测覆盖，但本模拟子集仅聚焦于北美大陆区域。本次模拟生成的SWOT KaRIn观测刈幅在跨刈幅方向上跨度达128千米，星下点间隙宽度为20千米。本产品可作为L2_HR_PIXC_V1产品的补充数据集，可为L2_HR_PIXC_V1的像元提供低噪声、经高程约束的地理定位信息（包含纬度、经度与高程）。此外，本产品还提供……
