abstract = "{We derive Greenland ice mass changes from the gravity recovery and
climate experiment (GRACE) and GRACE follow-on mascon solutions
and 30 input-output method (IOM) combinations, and conduct a
comprehensive comparison for the period 20022018. Using mascon
solutions as constraints, we identify an optimal IOM combination
to estimate the linear and quadratic trends for Greenland ice
mass change, which enables us to extend the analysis to 2023.
The IOM-estimated ice mass loss rate of 257.7 19.8 Gtyr$^{1}$
closely matches estimates from the three mascon solutions (258.9
13.2, 264.1 12.0, and 271.8 12.0 Gtyr$^{1}$, respectively),
provided by the Center for Space Research (CSR), Goddard Space
Flight Center (GSFC), and Jet Propulsion Laboratory (JPL). A
deceleration in ice mass losses is observed across all datasets,
with rates of 3.2 3.8, 4.5 2.2, 3.8 1.9, and 6.5 2.2 Gtyr$^{2}$
for the IOM combination, CSR, GSFC, and JPL mascon solutions,
respectively. Partitioning results suggest that surface mass
balance (SMB), solid ice discharge, and peripheral glaciers mass
balance contribute about 41, 50, and 9, respectively, to the
total loss, with the deceleration mainly originating from SMB.
Further decomposition of SMB reveals that runoff anomaly
accounts for 136 of SMB-related ice mass loss, with 37 offset by
positive precipitation anomaly. The observed deceleration in
Greenland ice mass loss that has only been evident in recent
years is temporally coherent with the quadratic increase in
cumulative snowfall anomaly (4.1 1.6 Gtyr$^{2}$).}",
