From: The state and fate of Glaciar Perito Moreno Patagonia

Fig. 2

a Ice surface elevation change rate map of the Glaciar Perito Moreno derived from TanDEM-X DEMs for the period 2019 to 2023. Hatched areas indicates data gaps. The solid black line indicates the central flow line as a reference profile. Black crosses represent the surface velocity extraction points V1-V4. Background: SRTM hillshade. b Surface elevation time series along a central flow line of Glaciar Perito Moreno. Date refers to the median acquisition time. The reference year is the SRTM DEM from 2000.02.16 (0-line). The light grey bar plots indicate the surface elevation. We discarded elevation information within the first 1500 metres due the glaciers retreat until 2024. c Surface velocity evolution from 2015 to 2023 at points V1-V4 along the central flow line. Each dot represents an individual measurement, and solid lines are weighted moving averages.
