Abstract
Greenland Ice Sheet is one of the key factors influencing global climate change. Its slight variations can lead to significant changes in sea level, making quantitative research on its mass balance of great scientific importance. This study employs ICESat and ICESat-2 satellite altimetry data from NASA’s ICESat (2003-2009) and ICESat-2 (2018-2020) missions to systematically quantify ice sheet elevation dynamics and associated to volumetric changes between 2003 and 2020, To mitigate intra-annual variability effects, analysis was constrained to temporally homologous quarter (January to April), ensuring interannual comparability through consistent seasonal sampling.
The dataset represents the mean elevation change of the Greenland Ice Sheet from 2003 to 2020. It consists of five TIF files, each corresponding to different years and basin delineations. The data are provided in the EPSG:3413 stereographic projection, with a pixel resolution of 5 km. Pixel values represent the annual mean elevation change in meters per year (m/yr).
