Journal ArticleDOI
Precise point positioning for the efficient and robust analysis of GPS data from large networks
TL;DR: This work determines precise GPS satellite positions and clock corrections from a globally distributed network of GPS receivers, and analysis of data from hundreds to thousands of sites every day with 40-Mflop computers yields results comparable in quality to the simultaneous analysis of all data.
Journal ArticleDOI
GRACE measurements of mass variability in the Earth system.
TL;DR: Geoid variations observed over South America that can be largely attributed to surface water and groundwater changes show a clear separation between the large Amazon watershed and the smaller watersheds to the north.
Journal ArticleDOI
Improved methods for observing Earth's time variable mass distribution with GRACE using spherical cap mascons
TL;DR: The mascon basis functions allow for convenient application of a priori information derived from near-global geophysical models to prevent striping in the solutions, and do not necessitate empirical filters to remove north-south stripes, lowering the dependence on using scale factors as discussed by the authors.
Journal ArticleDOI

TL;DR: In this article, high-resolution gravity data obtained from the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft show that the bulk density of the Moon's highlands crust is 2550 kilograms per cubic meter, substantially lower than generally assumed.
Journal ArticleDOI

TL;DR: The Gravity Recovery and Climate Experiment mission allows monitoring of changes in hydrology and the cryosphere with terrestrial and ocean applications and its contribution to the detection and quantification of climate change signals is focused on.
