Debris Emergence Elevations Geodatabase

DOI

This dataset contains estimates of debris emergence elevations for 974 debris-covered glaciers > 5 km^2 in High Mountain Asia, calculated for three compositing periods: 1985-1999, 2000 - 2010, and 2013 - 2017. Composites were constructed in Google Earth Engine with Landsat imagery, with relatively cloud-free imagery and pixels that were preferentially selected for high brightness temperatures to remove biases due to cloud or snow cover. The elevation of the transition zone between ice and debris was calculated as the median elevation of pixels that for each debris-covered glacier in the Randolph Glacier Inventory (RGI V5) using Shuttle Radar Topography Mission (SRTM) elevation data and the boundary between ice and debris delineated in the composites. Also included in this dataset are the average date of acquisition and day of year of acquisition for individual glacier composites, individual glacier mass balance trends from 2000 - 2017 (m w.e./yr; Brun et al. 2017), changes in glacier velocity (Dehecq et al. 2019), and modelled estimates of future glacier change (Kraaijenbrink et al., 2017).
