How to reach a few percent level in determining the Lense-Thirring effect?

, 2004
In this paper we discuss and compare a node-only LAGEOS-LAGEOS II combination and a node-only LAGEOS-LAGEOS II-Ajisai-Jason1 combination for the determination of the Lense-Thirring effect. The new combined EIGEN-CG01C Earth gravity model has been adopted.

Estimating effective elasticity in grounding zones of the Ross Ice Shelf with tidal flexure from ICESat-2

Journal of Glaciology
The grounding zones of Antarctic ice shelves are among the continent’s most dynamic regions, where floating ice shelves buttress grounded upstream ice and tidal forcing drives cyclic flexure at the ice–ocean–bed interface.

Lagrangian dynamical geography of the Gulf of Mexico

, 2017
We construct a Markov-chain representation of the surface-ocean Lagrangian dynamics in a region occupied by the Gulf of Mexico (GoM) and adjacent portions of the Caribbean Sea and North Atlantic using satellite-tracked drifter trajectory data, the ...

An improved model of the Earth's gravitational field: GEM-T1 [PDF]

Goddard Earth Model T1 (GEM-T1), which was developed from an analysis of direct satellite tracking observations, is the first in a new series of such models. GEM-T1 is complete to degree and order 36.

Using Multimission Satellite Altimetry to Monitor Subglacial Hydrological Activities in the Totten Basin, East Antarctica

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In East Antarctica, the largest thinning rates are observed at Totten Glacier in recent years. Hydrologic activity of the three active subglacial lakes (Totten1, Totten2, and Wilkes1) located on Totten Glacier may affect the ice sheet mass balance in the
