| 摘 要： | 随着遥感技术的不断进步，许多陆地水循环的变量已经能够通过遥感定量估算。遥感方法能够提供大范围、长周期的水循环变量数据，这极大地推进了人们对陆地水循环过程的认识和理解。阐述了遥感观测陆地水循环重要变量的基本原理，回顾了陆地水循环遥感主要技术方法的重要进展和最新成果，指出下一步可能的发展方向。尽管目前遥感技术具备获取大范围水循环关键变量的能力，但是遥感估算的水循环分量还难以满足基本的水量平衡，表明当前遥感数据的水文一致性还待加强。未来遥感陆地水循环研究的发展一方面需要新型传感器和平台来提供更高精度且时空一致的观测数据，另一方面需要开展大型地面水循环同步全过程观测试验来对遥感产品进行深入评估，以促进遥感技术在陆地水循环研究中的应用。

| Abstract: | Satellite remote sensing has made great strides in the last few decades, which enables the long-term consistent observations of many variables of the terrestrial water cycle and thus advances the understanding of the terrestrial water cycle. This paper reviews the principles of remote sensing in retrieving key variables of the terrestrial water cycle, illustrates the progress of satellite remote sen-sing in hydrological applications, and discusses the future direction. Although most of hydrological states and fluxes variables are observable by remote sensing, closing terrestrial water budget with the remote sensing products is still an open question, suggesting more efforts are needed to improve the hydrological consistency of the remote sensing products. In the future, efforts should be made to develop new generation sensors and platforms for the consistent remote sensing products with finer spatiotemporal resolution. At the same time, efforts should be devoted to the evaluation of remote sen-sing products of the terrestrial water cycle through carrying out integrated field experiments. |
