TL;DR: In this article, the authors determined the ice mass evolution of the Antarctica and Greenland ice sheets (AIS and GIS) and Gulf of Alaska (GOA) glaciers from a new GRACE global solution of equal-area surface mass concentration parcels (mascons) in equivalent height of water.

TL;DR: In this article, an approach similar in concept to altimetric methods that recovers sub-monthly mass flux at a high spatial resolution was presented, using 4° × 4° blocks at 10-day intervals, estimating the mass of surplus or deficit water over a 52° × 60° grid centered on the Amazon basin for July 2003.

TL;DR: The mass changes of the Gulf of Alaska (GoA) glaciers are computed from the GRACE inter-satellite range-rate data for the period April 2003-September 2007 as discussed by the authors.

TL;DR: In this paper, the Earth's gravity field determined solely from GRACE inter-satellite range-rate measurements using an improved method of accelerometer calibration and the use of a baseline state parameterization is presented.
