摘要
GRACE重力卫星为大尺度陆地水储量监测提供了新手段。目前,GRACE重力卫星数据已被广泛应用于全球尺度和流域尺度的陆地水储量反演。阐述了GRACE重力卫星的工作原理、发展历程和国内外研究现状,总结了GRACE重力卫星数据在地下水监测、蒸散发估算和干旱识别等领域的应用情况。归纳了当前存在的问题和改进方法,指出目前GRACE重力卫星数据存在空间分辨率较低、时间序列较短、存在一定误差等问题。提出了降尺度、多源数据融合等提高GRACE重力卫星数据的适应性和可靠性的途径和方向。研究成果能够为陆地水储量有效监测及GRACE卫星在水利相关领域的应用提供参考。
The GRACE gravity satellite has revolutionized large-scale terrestrial water storage monitoring.Currently,GRACE satellite data are widely used to estimate terrestrial water storage changes at both global and basin scales.This paper elaborated on the working principles,development history,and current research status of the GRACE gravity satellite in China and abroad.It summarized the application areas of GRACE data,such as groundwater monitoring,evapotranspiration estimation,drought identification,outlines existing challenges and potential improvements.At present,GRACE data still faces limitations including coarse spatial resolution,short time series,and various errors.We proposed that downscaling and multi-source data fusion can enhance the adaptability and reliability of GRACE data.This study may provide references for effective monitoring of terrestrial water storage and related applications,and offer support for addressing the global water crisis.
