| contents | For the Valles Calchaquíes region, Northwestern Argentina, we derived rock glacier surface velocities (in unit m/a) from multi-temporal aerial and satellite imagery using a feature tracking approch. The data covers three epochs (EPs), EP1 from 1968 to 2009, EP2 from 2009/2010 to 2020, EP3 from 2020 to 2023. Given the variable availablility of aerial and satellite images, the spatial coverage is not the same for all three EPs and the limit of detection is spatially variable. For our analysis, we used rock glacier outlines as published by the Inventario Nacional de Glaciares of Argentina (https://www.glaciaresargentinos.gob.ar/; polygon data can be downloaded there) that have a minimum area of 0.02 km². The data table provides information on the location of the rock glaciers investigated in our study, as well as mean surface velocities (in unit m/a) exceeding the limit of detection (in unit m/a) for each landform and epoch investigated. |
