Suyuparina catchment (Cordillera Vilcanota, Peru) glacier change datasets

Repository contains datasets associated with the following publication in the Journal of Glaciology. Methods used to derive each dataset are described in detail in the paper.King, O. et al. (2025) ‘The impact of supraglacial ice cliff and pond formation on debris-free, tropical glacier mass loss’, Journal of Glaciology, 71, p. e132. doi:10.1017/jog.2025.10109.Available files include:-PH1_11092024_DEM_1m.tif. 1m DEM generated from Pleiades stereo imagery acquired over the study site on the 11th September 2024. -2022_Drone_DEM_coreg_PH1_NK.tif. 1m DEM generated from a DJI drone survey over the Suyuparina Glacier in 2022. The drone DEM has been coregistered to the 2024 PH1 DEM the techniques described by Nuth and Kääb (2011) (https://tc.copernicus.org/articles/5/271/2011/tc-5-271-2011.html)-2016_2024_PH1_dhdt.tif. Surface elevation change rate (dhdt) data derived by the differencing of PH1 DEMs generated from stereo pairs acquired in 2016 and 2024.-1979_KH9_PC_2024_PH1_dhdt.tif. Surface elevation change rate (dhdt) data derived by the differencing of the 2024 PH1 DEM with a DEM generated from Hexagon KH-9 panoramic camera imagery acquired in 1979. -PH1_2016/2024_aspect.tif. Surface aspect grid derived from the 2016/2024 PH1 DEM.-PH1_2016/2024_slope.tif. Surface slope grid derived from the 2016/2024 PH1 DEM.-PH1_2016/2024_TPI.tif. Topographic Position Index (TPI) grid derived from the 2016/2024 PH1 DEM.
