Recent contributions of glaciers and ice caps to sea level rise, from GRACE
Glaciers and ice caps (GIC) are important contributors to present-day global mean sea-level rise (SLR). Most previous global mass balance estimates for GIC rely on interpolation of sparse mass balance measurements, representing a small fraction of the GIC area. Instead, we here perform a global, sim...
