This data set includes annual dynamic ice sheet thickness change rate time series reconstructed at 16,136 locations on the Greenland Ice Sheet. Time series were derived from laser altimetry data collected from 1993 to 2017 by using the Surface Elevation Reconstruction and Change (SERAC) approach (Schenk and Csatho, 2012). Ice thickness changes caused by surface processes were modeled by RACMO 2.3p2 (Noël et al., 2019) and subtracted from the total elevation change to obtain ice thickness changes due to ice dynamics. Annual rates were computed from polynomial fit (max. 3rd, order) or ALPS (Shekhar et al., 2021). Parameters: Name Description PointID Unique ID assign to location X X coordinate of time series given in meter, UTM projection (zone N24, EPSG: 32624) Y Y coordinate of time series given in meter, UTM projection (zone N24, EPSG: 32624) ObsInt Length of time series (month, from first to last observational epoch used) Hrange_flag Set according to the range of thickness change (from original time series before outlier removal). Hrange_flag=0, range of thickness change less than 5 m, annual rates computed with polynomial modeling (max 3rd order/cubic), Hrange_flag=1, range of thickness change more than 5 m, annual rates computed with ALPS. POL9394 Annual rate from polynomial interpretation for balance year 1993/94 (September 1 1993 – August 31, 1994), all years until balance year 2016/17. ALPS9394 Annual rate from ALPS modeling for balance year 1993/94 (September 1 1993 – August 31, 1994), all years until balance year 2015/16.
