Le résumé fourni par la source

This repository contains the data supporting the study titled Mass changes of the Antarctic Peninsula ice sheet and peripheral glaciers, 2007–2021 from Bernat et al. (https://doi.org/10.5194/egusphere-2026-729). The processing of the data deposited in the repository is detailed in the mentioned study. The repository contains the following files : Elevation change maps in .tif format- dhdt_map_AP_2007_2021_obs_30m.tif : The elevation change rate map obtained from observations at 30 m spatial resolution (SPOT5-HRS versus REMA DEMs).- dhdt_map_AP_2007_2021_interpolated_30m.tif : The elevation change rate map obtained from observations and interpolation at 30 m spatial resolution (SPOT5-HRSversus REMA DEMs).- dhdt_map_AP_2007_2021_corrected_30m.tif : The elevation change rate map obtained from observations and interpolation at 30 m spatial resolution (SPOT5-HRSversus REMA DEMs), corrected for Firn Air Content (FAC), Glacial Isostatic Adjustment (GIA) and Elastic Rebound (ELR).- dhdt_map_AP_2007_2021_FAC_100m.tif : The FAC correction applied to obtain the corrected elevation changes.- dhdt_map_AP_2007_2021_GIA_100m.tif : The GIA correction applied to obtain the corrected elevation changes.- dhdt_map_AP_2007_2021_ELR_900m.tif : The ELR correction applied to obtain the corrected elevation changes. Mean elevation changes in .csv format- results_SIL20_AP_2007_2021 : The glacier-wide variables are indicated for each glacier from Silva et al. (2020) outlines and are described below. > area_tot_km2 : glacier area in square kilometers> ratio_obs_tot : ratio between the observed area and the total area, no unit> dhdt_corr(myr-1) and final_unc_dhdt_(myr-1) : mean ice elevation change rate and associated uncertainty in m/yr> dhdt_(myr-1) : mean elevation change rate in m/yr> dhdt_obs_err_(myr-1)_W : mean observed elevation change uncertainty weighed by the observed area ratio in m/yr> dhdt_interp_err_(myr-1)_W : mean interpolated elevation change rate uncertainty weighed by the interpolated area ratio in m/yr> dFACdt_(myr-1) and std_FAC_(myr-1) : mean FAC elevation change rate and associated uncertainty in m/yr> dFACdt_GEMB_(myr-1), dFACdt_IMAU_(myr-1), dFACdt_GSFC_(myr-1) and dFACdt_MAR_(myr-1) : mean FAC elevation change rate for each firn densification model individually in m/yr> GIA_(myr-1) and std_GIA_(myr-1) : mean GIA elevation change rate and associated uncertainty in m/yr> GIA_Peltier_(myr-1), GIA_Caron_(myr-1) and GIA_Whitehouse_(myr-1) : mean GIA elevation change rate for each model individually in m/yr> elastic_rebound_(myr-1) : mean elastic rebound elevation change rate in m/yr> dMdt_corr(Gtyr-1) : mass change rate in Gt/yrfinal_unc_dMdt_(Gtyr-1) : mass change rate uncertainty in Gt/yr - results_RGI7_AP_2007_2021 : Same variables as the file above, for RGI7 (RGI Consortium, 2023) glaciers.
