Jason测高卫星和GRACE重力卫星在陆地水资源及洪水监测中的应用

Application of Jason and GRACE Satellites in Terrestrial Water Resources and Flood Monitoring

Jason测高卫星和GRACE重力卫星作为大尺度水文监测手段的有力补充,对变化环境下的全球和区域水资源管理和灾害预警具有重要意义。本文介绍了Jason测高卫星和GRACE重力卫星数据,归纳了国内外学者基于Jason测高卫星和GRACE重力卫星开展的陆地水资源与洪水事件监测研究情况,并分析了Jason测高卫星和GRACE重力卫星目前面临的挑战与未来的展望。

As powerful supplements to large-scale hydrological monitoring techniques, Jason and GRACE (Gravity Recovery and Climate Experiment) satellites are of great significance for global and regional water re-sources management and disaster warning under changing environments. This study introduces the Jason altimetry satellite and GRACE data, and summarizes their applications and relevant researches on terrestrial water resources and flood monitoring. Finally, the current challenges and prospects of Jason and GRACE satellites are demonstrated.
