Abstract :

[en] We examine data continuity between the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (FO) missions over Greenland and Antarctica using independent data from the mass budget method, which calculates the difference between ice sheet surface mass balance and ice discharge at the periphery. For both ice sheets, we find consistent GRACE/GRACE-FO time series across the data gap, at the continental and regional scales, and the data gap is confidently filled with mass budget method data. In Greenland, the GRACE-FO data reveal an exceptional summer loss of 600 Gt in 2019 following two cold summers. In Antarctica, ongoing high mass losses in the Amundsen Sea Embayment of West Antarctica, the Antarctic Peninsula, and Wilkes Land in East Antarctica cumulate to 2130, 560, and 370 Gt, respectively, since 2002. A cumulative mass gain of 980 Gt in Queen Maud Land since 2009, however, led to a pause in the acceleration in mass loss from Antarctica after 2016.

This work was performed at the University of California Irvine, Department of Earth System Science, and at NASA's Jet Propulsion Laboratory under a contract with NASA's program. The GRACE data used in this paper are available at Caltech's Jet Propulsion Laboratory (grace.jpl.nasa.gov). The ice velocity data are available as MEASURES products at the National Snow and Ice Data Center (NSIDC) for Greenland (nsidc.org/data/nsidc-0478) and Antarctica (nsidc.org/data/nsidc-0720). The ice thickness data are available at the NSIDC as BedMachine Greenland (nsidc.org/data/IDBMG4) and BedMachine Antarctica (nsidc.org/data/nsidc-0756). The SMB data are available on the PANGAEA database (doi.pangaea.de/10.1594/PANGAEA.896940). GRACE data from the figures are posted online (ess.uci.edu/~velicogna/grace-fo.php).
