     abstract = "{The new photon-counting laser altimetry satellite ICESat-2 was
        successfully launched on September 15, 2018 with an
        unprecedented ice surface elevation measurement accuracy of 2-4
        cm. It is meaningful for accurately estimating volumetric
        changes in the Antarctic Ice Sheet. Cross-validation of
        different types of data, especially comparison with in-situ
        data, is important for the ice sheet mass balance results of a
        new satellite. This paper proposes an elevation-difference
        method of grid elevation change rate model, based on ICESat-2
        ATL11 elevation time series data, to distinguish the linear
        change trend of ice sheet surface elevation from the elevation
        change resulting from periodic precipitation. In order to
        compare the estimated elevation-change rate with the flux
        computed from in-situ snow stake velocity measurements and
        GRACE-FO gravity survey data, we made corrections for firn air
        content, elastic, and glacier isostatic adjustment. Based on the
        ATL11 data from 2019 to 2023, our results show that the ice
        sheet change in Basin 11 along the CHINARE traverse is from
        \raisebox{-0.5ex}\textasciitilde0.019 m yr-1 to
        \raisebox{-0.5ex}\textasciitilde0.121 m yr-1, and the mass
        balance in the upstream of the traverse in Basin 11 is
        \raisebox{-0.5ex}\textasciitilde1.9{\ensuremath{\pm}}0.2 Gt
        yr-1. It is comparable to
        \raisebox{-0.5ex}\textasciitilde2.4{\ensuremath{\pm}}1.2 Gt yr-1
        from GRACE-FO during the same time period. Furthermore, the flux
        across traverse-11.9{\ensuremath{\pm}}1.1 Gt yr-1 is comparable
        to that of
        \raisebox{-0.5ex}\textasciitilde-9.7{\ensuremath{\pm}}0.9 Gt
        yr-1 across the same flux gate during 1997-2009 which is
        calculated based on GNSS-derived ice velocity observations,
        considering the time period difference and uncertainties.}",
