The Review of GRACE Data Applications in Terrestrial Hydrology Monitoring

Abstract

The Gravity Recovery and Climate Experiment (GRACE) satellite provides a new method for terrestrial hydrology research, which can be used for improving the monitoring result of the spatial and temporal changes of water cycle at large scale quickly. The paper presents a review of recent applications of GRACE data in terrestrial hydrology monitoring. Firstly, the scientific GRACE dataset is briefly introduced. Recently main applications of GRACE data in terrestrial hydrological monitoring at large scale, including terrestrial water storage change evaluation, hydrological components of groundwater and evapotranspiration (ET) retrieving, droughts analysis, and glacier response of global change, are described. Both advantages and limitations of GRACE data applications are then discussed. Recommendations for further research of the terrestrial water monitoring based on GRACE data are also proposed.

Recent changes in terrestrial water storage in the Upper Nile Basin: an evaluation of commonly used gridded GRACE products

“…1) surface water storage in rivers, lakes, and wetlands ( SWS), soil moisture storage ( SMS), ice and snow water storage ( ISS), and groundwater storage ( GWS). Over the last decade, GRACE measurements have become an important hydrological tool for quantifying basin-scale TWS (Güntner, 2008;Xie et al, 2012;Hu and Jiao, 2015) and are increasingly being used to assess spatio-temporal changes in specific water stores Shamsudduha et al, 2012;Jiang et al, 2014;Castellazzi et al, 2016;Long et al, 2016;Nanteza et al, 2016) where timeseries records of other individual freshwater stores are available (Eq. 1).…”

Investigation of the Correlation Between Grace TWS and Soil Moisture in Sarakhs Catchment

“…GRACE can extract realistic spatiotemporal variations of vertically integrated measurement of water storage (groundwater, soil moisture, surface water, snow water, vegetation water, etc.) at the precision of tens of mm of equivalent water height at large scale [4]. The TWS anomalies can be written as a sum of the changes in soil moisture (ΔSM), snow water equivalent (ΔSWE), and groundwater (ΔGW) [6]:…”

Climate Change in the Last Century and Its Impact on Water Cycle in Central Asian Aridzone

“…However, the scarcity of in-situ measurement site in the study area limits the understanding of the water cycle variation in the study area. Traditional monitoring of terrestrial hydrology relies on costly and time-consuming field data logging and model simulations [Jiang et al, 2014]. Research projects have been undertaken on aridzone water cycle modelling using field data measurements.…”
