IPY: Investigation of Antarctic Ice Sheet Mass Balance From Satellite Gravity Measurements

Entry ID: chen_0632195

[ Update this Record ]

Summary

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
