Data sets

Supraglacial features of debris covered glaciers in the Himalaya from Landsat-8 spectral umixing and Pleiades Adina E. Racoviteanu, Lindsey Nicholson, and Neil Glasser https://doi.org/10.5281/zenodo.4421857

Short summary

Supraglacial debris cover comprises ponds, exposed ice cliffs, debris material and vegetation. Understanding these features is important for glacier hydrology and related hazards. We use linear spectral unmixing of satellite data to assess the composition of map supraglacial debris across the Himalaya range in 2015. One of the highlights of this study is the automated mapping of supraglacial ponds, which complements and expands the existing supraglacial debris and lake databases.
