“…Area S of glaciers in the year of RES measurements, mean thickness of glacier H mean , average thickness of cold ice H avcold and temperate ice H avtemp , volume of cold ice V cold and temperate ice V temp , measured total volume of glaciers V Σ , volume fraction of temperate ice in total volume of glacier FTIV=V temp /V Σ , and water storage W s =W×V temp in temperate ice with water content W Data for area S, mean ice thickness H mean , total volume V Σ of glaciers and errors in their estimates are given byLavrentiev et al (2019);c) Values of water storage W s in polythermal glaciers are given for estimated average water content W in temperate ice 2%In polythermal glaciers, the RWV in temperate ice v temp can range from 156 to 168 m/mcs; i.e., on average v temp =162 m/mcs, ε vtemp =± 6 m/mcs and depends on water content W in temperate ice. At maximum thickness of temperate ice H temp =240 m, ε Htemp = ±5.7 m (±2.4%).…”
