Observations: Oceanic Climate Change and Sea Level
The oceans are warming. Over the period 1961 to 2003, global ocean temperature has risen by 0.10°C from the surface to a depth of 700 m. Consistent with the Third Assessment Report (TAR), globalExpand
Crustal Dilatation Observed by GRACE After the 2004 Sumatra-Andaman Earthquake
We report the detection of an earthquake by a space-based measurement. The Gravity Recovery and Climate Experiment (GRACE) satellites observed a ±15-microgalileo gravity change induced by the greatExpand
Precision orbit determination for TOPEX/POSEIDON
The TOPEX/POSEIDON mission objective requires that the radial position of the spacecraft be determined with an accuracy better than 13 cm RMS (root mean square). This stringent requirement is anExpand
Accuracy assessment of recent ocean tide models
Over 20 global ocean tide models have been developed since 1994, primarily as a consequence of analysis of the precise altimetric measurements from TOPEX/POSEIDON and as a result of parallelExpand
Non-isotropic filtering of GRACE temporal gravity for geophysical signal enhancement
SUMMARY Monthly mass variations within the Earth system produce temporal gravity changes, which are observable by the NASA/GFZ Gravity Recovery and Climate Experiment (GRACE) twin-satellite system.Expand
The Joint Gravity Model 3
An improved Earth geopotential model, complete to spherical harmonic degree and order 70, has been determined by combining the Joint Gravity Model 1 (JGM 1) geopotential coefficients, and theirExpand
Time‐variable aliasing effects of ocean tides, atmosphere, and continental water mass on monthly mean GRACE gravity field
[1] The Gravity Recovery and Climate Experiment (GRACE) satellite mission will provide new measurements of Earth's static and time-variable gravity fields with monthly resolution. The temporalExpand
Progress in the determination of the gravitational coefficient of the Earth
In most of the recent determinations of the geocentric gravitational coefficient (GM) of the Earth, the laser ranging data to the Lageos satellite have had the greatest influence on the solution.Expand
Vertical crustal motion determined by satellite altimetry and tide gauge data in Fennoscandia
[1] We present a new method of combining satellite altimetry and tide gauge data to obtain improved estimates of absolute (or geocentric) vertical crustal motion at tide gauges within a semi-enclosedExpand
Lake volume and groundwater storage variations in Tibetan Plateau's endorheic basin
The Tibetan Plateau (TP), the highest and largest plateau in the world, with complex and competing cryospheric‐hydrologic‐geodynamic processes, is particularly sensitive to anthropogenic warming. TheExpand
