With the threat of water shortages intensifying, the need to identify the terrestrial water storage TWS variation in the Tarim River Basin TRB becomes very significant for managing its water resource. Early results will be reported at the meeting. Despite the successful applications of GRACE in studying global groundwater storage change, there are still some major challenges limiting the application and interpretation of GRACE data. To be consistent, we are in the process of generating a climatology of estimated soil moisture and ground water based on m year Catchment model simulation which will subsequently be used to convert seven years of GRACE assimilated fields into soil moisture and groundwater percentiles. To mitigate this subliminal problem, it is essential to enhance our level of understanding about the dynamics of global and regional fresh water resources which include surface and ground water reserves. Global averages of TWSC were partitioned nearly equally between soil moisture and snow water equivalent, while zonal averages of TWSC revealed the importance of soil moisture storage at low latitudes and snow storage at high latitudes. Observations of terrestrial water storage TWS from the Gravity Recovery and Climate Experiment GRACE satellite mission have a coarse resolution in time monthly and space roughly , km sup 2 at midlatitudes and vertically integrate all water storage components over land, including soil moisture and groundwater.

At this stage we provide a preliminary evaluation of the GRACE assimilated moisture and indicator fields. We expect global hydrological models as WHGM to profit from such accurate outcomes.

The spatiotemporal evolution of GRACE data reflects consistent patterns with that of several hydroclimatic variables and also shows that most of the water loss has occurred in the northern parts of India.

What makes GRACE unique among Earth Ghj satellite systems is ble-03 it is able to monitor variations in water stored in all forms, from snow and surface water to soil moisture to groundwater in the deepest aquifers. A priori ground-based data used in forward modeling can provide a powerful tool for explaining the distribution of signal gains or losses caused by low-pass filtering in specific regions of interest and should be very useful for more reliable estimation of groundwater storage changes using GRACE satellites.

In particular, degraded battery capacity limits the availability of power in certain orbital configurations, so that the accelerometers must be turned off for approximately one month out of six. Terrestrial water storage changes over Xinjiang extracted by combining Gaussian filter and multichannel singular spectrum analysis from GRACE. Over grasslands and temperate forests in the Southeast Ob and South Yenisei, wetting and cooling lead to a dominant temperature constraint due to the relaxation of TWS constraints.

However, because of its spatial and temporal gaps and cost, it is typically difficult to ggm large scale, continuous observations. Regional groundwater storage changes in Illinois are estimated from monthly GRACE total water storage change TWSC data and in blud-03 measurements of soil moisture for the period Is this the largest recovery that California can expect?

Our results, estimated as basin averages, indicate negative trends in the maximums of TWF peaks that reach up to The bue-03 droughts, of which the HRB has sustained for more than 5 years, began in mid We then estimate the stress change at the Earth’s surface caused by elastic loading of mass change associated with the inferred TWS change.

Conversely, the Queen Maud Land sector experienced a large snowfall in and has now resumed to a zero mass gain since Although they detected the same droughts during warm seasons, drought signatures in GRACE derived TWS exhibited greater persistence than those in NDVI throughout all seasons, in part due to limitations associated with the seasonality of vegetation.

To be consistent, we generated a climatology of estimated soil moisture and ground water based on a year Catchment model simulation, which was used to convert seven years of GRACE assimilated fields into drought indicator percentiles. The spatial resolution of the GRACE solutions was unfortunately limited to degree around km by the presence of noise for the higher harmonic degrees.

In order to enhance model-based estimates of TWS while effectively adding 2020 in space and time to the coarse-scale TWS retrievals, a multi-variate, multi-sensor data assimilation framework is presented here blus-03 simultaneously assimilates gravimetric retrievals of TWS in conjunction with passive microwave PMW brightness temperature Tb observations over snow-covered terrain.

A synthetic assimilation experiment is presented for the Hhm river basin in Russia. To improve the accuracy of groundwater estimates and allow the representation of the WTD at fine spatial scales we implemented a gh approach that enables blye-03 large-scale data integration system to assimilate GRACE data. These results demonstrate that satellite TWS and SM measurements can be jointly assimilated to produce improved water balance component estimates.

The new algorithm differs in how the analysis increments are computed and applied. This study improves these estimates by defining human water use in two ways. The global time-variable gravity products from GRACE continue to provide unique and important measurements of vertically integrated terrestrial water storage TWS.

Here we holistically test whether California state water resources have fully 220204 in the Sacramento, San Joaquin, and Tulare Lake basins of California, using remote sensing satellite observations, in situ measurements, and numerical models.

The Drought Monitors combine several short- and long-term drought indicators expressed in percentiles as a reference to their historical frequency of occurrence.

In situ groundwaterdata are only archived and made bpue-03 by a few countries. The initial ranges of soil hydraulic parameters are taken in correspondence with the values available from the literature based on FAO. Did the groundwater recover?

The results indicate the YRB experienced increased wetness during the study period, with WSD values increasing at a rate of 5. Even though many studies recommend GRACE observations to be used over regions larger thankm2 -km2 area, results show GRACE remote sensing and GLDAS modeled groundwater change information are skillful to monitor the large mass changes occured as a result of the excessive groundwater exploitation over Konya Closed Basin with 50, km2 area.

Recently, we have developed an approach to analyze and calibrate basin scale TWS estimates directly from the inter-satellite observation residuals. This trend was not reproduced bluw-03 the model.

In the majority of the locations with high signal to noise ratio, both short and long-term fluctuations of total terrestrial water storage can be reconstructed to a large degree based on available atmospheric forcing. The downscaling model, constructed through calibration and sensitivity analysis, was used to estimate TWS anomaly for watersheds ranging from to 20, km2 in the study area.

At the semi-annual period, the GRACE estimates are also generally closer to the geodetic residual, but with some biases in phase or amplitude due mainly to some aliasing errors at near semi-annual period from geophysical models.
