Abstract:
This award supports a project to assess Antarctic ice sheet mass balance at both continental and regional spatial scales, using high-accuracy satellite gravity measurements from the NASA Gravity Recovery and Climate Experiment (GRACE) mission.
Purpose:
This study will provide improved assessments of Antarctic ice mass balance at continental, regional, and catchment basin scales using GRACE gravity data with unprecedented accuracy
Description:
GRACE, twin satellites launched in March 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems. These discoveries could have far-reaching benefits to society and the world's population.
