“…This system can also provide high-resolution products, including soil moisture and snow water equivalent data. Different LSMs of GLDAS can generally provide consistent timing of SMS changes, but may derive considerable differences in SMS magnitude under extremely dry and extremely wet conditions [45], which is most likely caused by the different evapotranspiration parameterization schemes of different LSMs [45,46]. In this study, soil moisture (1.0 degree/monthly data) is estimated by averaging the results from five simulations of the GLDAS system [44], which span from July 2003 to December 2010.…”

Over the past four decades, land use/land cover (LU/LC) change, coupled with persistent drought, has resulted in the decline of groundwater levels in Horqin Sandy Land. Accordingly, this study quantifies changes in LU/LC and groundwater storage (GWS). Furthermore, it investigates the effects of LU/LC changes on GWS. GWS changes are estimated using Gravity Recovery and Climate Experiment (GRACE) data and ground-based measurements obtained from July 2003 to December 2010. Soil moisture and snow water equivalent data derived from the Global Land Data Assimilation System (GLDAS) are used to isolate GWS changes from GRACE-derived terrestrial water storage changes. The result shows that the groundwater depletion rate in Horqin Sandy Land is 13.5˘1.9 mm¨year´1 in 2003-2010, which is consistent with the results of monitoring well stations. LU/LC changes are detected using bitemporal imageries (2003 and 2010) from Landsat Thematic Mapper through the post-classification comparison method. The result shows that LU/LC significantly changed during the aforementioned period. Bare soil and built-up land have increased by 76.6% and 82.2%, respectively, while cropland, vegetation, and water bodies have decreased by 14.1%, 74.5%, and 82.6%, respectively. The analysis of GWS and LU/LC changes shows that LU/LC changes and persistent drought are the main factors that affect groundwater resources.

“…A flash drought during the summer of 2013 affected 13 provinces in southern China and damaged over 2 million hectares of crops in Guizhou and Hunan provinces alone (http://www.chinaam.com.cn). To mitigate the impacts from drought hazards through increasing the preparedness, real-time monitoring and timely early warning of short-term droughts with advanced remote sensing technology [Svoboda et al, 2002;Long et al, 2013;Zhang and Jia, 2013;Tang et al, 2014;Thomas et al, 2014] and the state-of-the-art climate forecast models are widely investigated in the literature.…”

Severe short‐term (monthly to seasonal) droughts frequently occurred over China in recent years, with devastating impacts on crop production. This study assesses the capability of microwave remote sensing in detecting soil moisture (agricultural) droughts over China and in providing early warnings. The 22 year (1992–2013) European Space Agency satellite soil moisture retrievals are compared against the in situ observations at 312 stations in China, the global soil moisture reanalysis, and the observed rainfall deficit. Both the reanalysis and remote sensing products can only detect less than 60% of drought months at in situ station scale, but they capture the interannual variations of short‐term drought area at river basin scales quite well. As compared with reanalysis, the passive and merged microwave products have better drought detection over sparsely vegetated regions in northwestern China and the active microwave product with better vegetation penetration works the best in eastern China.

“…Because of their sensitivity to water amount over large areas, GRACE data can also be a useful tool for identifying impact caused by extreme climate events like droughts and floods, or for tracking climate change's influence on local water resources (Andersen et al, 2005;Long et al, 2013;Phillips et al, 2012). Scientists found that inclusion of GRACE-based total water storage information allows the predisposition of a river basin to flooding to be assessed as much as 5-11 months in advance (Reager et al, 2014).…”

Abstract. We applied Gravity Recovery and Climate Experiment (GRACE) Tellus products in combination with Global Land Data Assimilation System (GLDAS) simulations and data from reports, to analyze variations in terrestrial water storage (TWS) in China as a whole and eight of its basins from 2003 to 2013. Amplitudes of TWS were well restored after scaling, and showed good correlations with those estimated from models at the basin scale. TWS generally followed variations in annual precipitation; it decreased linearly in the Huai River basin (−0.56 cm yr −1 ) and increased with fluctuations in the Changjiang River basin (0.35 cm yr −1 ), Zhujiang basin (0.55 cm yr −1 ) and southeast rivers basin (0.70 cm yr −1 ). In the Hai River basin and Yellow River basin, groundwater exploitation may have altered TWS's response to climate, and TWS kept decreasing until 2012. Changes in soil moisture storage contributed over 50 % of variance in TWS in most basins. Precipitation and runoff showed a large impact on TWS, with more explained TWS in the south than in the north. North China and southwest rivers region exhibited long-term TWS depletions. TWS has increased significantly over recent decades in the middle and lower reaches of Changjiang River, southeastern coastal areas, as well as the Hoh Xil, and the headstream region of the Yellow River in the Tibetan Plateau. The findings in this study could be helpful to climate change impact research and disaster mitigation planning.
