Measurements from the debris-covered Imja-Lhotse Shar Glacier (2013-2014)

These data are from the debris-covered portion of Imja-Lhotse Shar Glacier (27.901N, 86.938E, ~5050 m a.s.l.) located in the Nepal Himalaya that were collected during three field expeditions between September 2013 and November 2014. The data includes debris thickness measurements derived primarily by manual excavation, debris temperature measurements from thermistors located at the surface or within the debris, ablation stakes, and high-resolution digital elevation models used to estimate the surface roughness. Below is a brief description of the various datasets: - 15.03743_rounce2014-hd.csv: debris thickness measurements (m) from Rounce and McKinney (2014) and Rounce et al. (2015). - 15.03743_rounce2014-ts.csv: debris temperature measurements (K) where the depth is reported in cm from Rounce and McKinney (2014). - 15.03743_rounce2015-melt.csv: ablation stake measurements from the period May 18 - Nov 9 2014 detailed in Rounce et al. (2015). - 15.03743_rounce2015-ts.csv: debris temperature measurements (K) where the depth is reported in cm from Rounce et al. (2015). - Site_XX_DEM_1cm.tif: digital elevation model used to estimate surface roughness from Rounce et al. (2015). ----- Citing datasets ----- If using the debris thickness measurements (15.03743_rounce2014-hd.csv) or temperature data from September 2013 (15.03743_rounce2014-ts.csv), please cite: Rounce, D.R. and McKinney, D.C.
