GRACE mass balance estimates for all the Earth's ice-covered regions
We have used GRACE satellite gravity measurements to construct 2003-2010 mass loss estimates for all the world's mountain glacier systems and ice caps (GIC's), as well as for Greenland and Antarctica. We find that the GIC's, excluding the Greenland and Antarctic peripheral glaciers an...
