abstract = "{When using GRACE and GRACE-FO for mass change estimates in Antarctica,
multiple different solutions can be used. We compared five
different Level-2 solutions and found that they agree very well
on both trend estimation and monthly mass change when using a
point mass inversion method. What are the main findings? The
five different Level-2 solutions result in comparable mass
change estimates for Antarctica, and the Glacial Isostatic
Adjustment (GIA) error is the dominant error source in the trend
estimation. We can observe a big mass accumulation in the East
Antarctic Basins 12 and 13 during 2021, 2022, and 2023. The five

Antarctic Basins 12 and 13 during 2021, 2022, and 2023. What is
the implication of the main findings? When estimating mass
change from GRACE and GRACE-FO, the choice of solution is a
negligible error source compared to the GIA error. Mass change
in Antarctica is not linear, and trend estimation is still
dependent on the chosen timespan. When estimating mass change
from GRACE and GRACE-FO, the choice of solution is a negligible
error source compared to the GIA error. Mass change in
Antarctica is not linear, and trend estimation is still
dependent on the chosen timespan. Several Level-2 solutions for
the GRACE(-FO) gravity field exist. We compare five of these
solutions using a mascon inversion method to estimate gridded
mass change in Antarctica from gravity field grids at orbit
height. We compare the mass change for all of Antarctica, as
well as for 27 drainage basins. All five solutions show
consistent negative mass trends for the period between April
2002 and January 2025 and show a mass accumulation in the East
Antarctic basins 12 and 13 during the years 2021, 2022, and the
beginning of 2023 but also a rapid mass loss starting in May
2023. While there are regional differences, the error from the
Glacial Isostatic Adjustment model exceeds the differences
between the solutions looked at in this study.}",
