As the largest groundwater drainage region in China, per capita water resources North China Plain (NCP) account for only one-seventh of country’s available resources. Currently, NCP is experiencing a serious shortage due to overexploitation and subsequent series natural disasters. Thus, accurate regional assessments effective resource management policies are critical importance. To accomplish t...

The Advanced Microwave Scanning Radiometer 2 (AMSR2) onboard the Global Change Observation Mission 1–Water (GCOM-W1) was launched by the Japan Aerospace Exploration Agency (JAXA) in May 2012. The AMSR2 is the follow-on model of the AMSR-Earth Observing System (AMSR-E) onboard the Aqua satellite. An assessment of the reliability of the soil moisture estimations from the newly launched passive se...

Groundwater plays a key role in maintaining the ecology and environment in the hyperarid Qaidam Basin (QB). Indirect evidence and data from sparse observation wells suggest that groundwater in the QB is increasing but there has been no regional assessment of the groundwater conditions in the entire basin because of its remoteness and the severity of the arid environment. Here we report changes ...

Accurately assessing groundwater storage changes in Niger is critical for long-term water resource management but difficult due to sparse field data. We present a study of and recharge Southern Niger, computed using data from NASA Gravity Recovery Climate Experiment (GRACE) mission. compute anomaly estimate by subtracting the surface provided Global Land Data Assimilation System (GLDAS) model G...

Abstract The gap between the Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-on mission (GRACE-FO) is a crucial problem, leading to discontinuous global mass change information from time-variable gravity field solutions. We aim use improved Multichannel Singular Spectrum Analysis (MSSA) fill reconstruct continual signals in this study. one-year filled with MSSA based on Release 06 ...

Soil moisture is one of the most important parameters affecting dust emission flux. This study was conducted to investigate effects soil on vertical flux in central plateau region Iran. In this study, WRF-Chem (Weather Research and Forecast with Chemistry) model, GOCART (Global Ozone Chemistry Aerosol Radiation Transport) scheme, used estimate during a major storm from 19 21 July 2015, discrimi...

Large uncertainties exist in the available hydrology loading prediction models, and currently no consensus is reached on which model superior or appears to represent nature a more satisfactory way. This study discusses noise characterization combination of vertical loadings predicted by different reanalysis (e.g., MERRA, GLDAS/Noah, GEOS-FPIT, ERA interim). We focused predictions time span from...

<p>GRACE (Gravity Recovery and Climate Experiment) is a satellite mission that can monitor mass distributions in the Earth system, which closely related to consequences of climate change. This gravimetric allows obtain monthly variations Earth’s gravity field, be associated with water variations, after removing effects oceanic tides solid Earth, as well non-tidal atmospheric contributions...

[1] High-quality continental-scale snow water equivalent (SWE) data sets are generally not available, although they are important for climate research and water resources management. This study investigates the feasibility of a framework for developing such needed data sets over North America, through the ensemble Kalman filter (EnKF) approach, which assimilates the snow cover fraction observed...
