A new functional model is proposed for gravity field modeling on the basis of KBR data from the GRACE satellite mission. This functional model explicitly connects a linear combination of gravitational potential gradients with a linear combination of range-rate measurements at several successive epochs. The system of observation equations is solved in the least-squares sense by means of the pre-...

Observations from the Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) missions can be used to estimate gravimetric excitation of polar motion (PM), which reflects contribution mass changes in continental hydrosphere cryosphere PM variation. Many solutions for Earth’s gravity field variations have been developed by institutes around world based on GRACE/GRACE-FO data; ...

[1] A long-standing challenge for hydrologists has been a lack of observational data on global-scale basin hydrological behavior. With observations from NASA's Gravity Recovery and Climate Experiment (GRACE) mission, hydrologists are now able to study terrestrial water storage for large river basins (>200,000 km2), with monthly time resolution. Here we provide results of a time series model of ...

For 15 years, the Gravity Recovery and Climate Experiment (GRACE) mission have monitored total water storage (TWS) changes. The GRACE ended in October 2017, 11 months later, Follow-On (GRACE-FO) was launched May 2018. Bridging gap between both missions is essential to obtain continuous mass To fill gap, we propose a new approach based on remove–restore technique combined with an autoregressive ...

The aims of the “Visualization in Parallel” (Vipar) project is to produce a comprehensive environment for the development of parallel visualization modules in systems such as the Application Visualization System (AVS), Iris Explorer, IBM Data Explorer (DX) and Khoros. This paper presents an overview of the project and describes the libraries developed to support the first phase of the work whic...

Evapotranspiration (ET) plays an important role in the hydrological cycle of river basins. Studying ET Yellow River Basin (YRB) is greatly significant for scientific management water resources. Here, we made full use advantages Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) gravity satellites monitoring large-scale changes to calculate terrestrial storage anomaly (TW...

Drought is a complex natural hazard which can have negative effects on agriculture, economy, and human life. In this paper, the primary goal is to explore the application of the Gravity Recovery and Climate Experiment (GRACE) gravity satellite data for the quantitative investigation of the recent drought dynamic over the arid land of northwestern China, a region with scarce hydrological and met...

New satellite missions are returning high precision, time-varying, satellite measurements of the Earth’s gravity field. The GRACE mission is now in its calibration/validation phase and first results of the gravity field solutions are imminent. We consider here the possibility of external validation using data from the superconducting gravimeters in the European sub-array of the Global Geodynami...
