Short summary
Light-absorbing particles on surface ice in ablation areas can accelerate glacier melting and shrinkage. Snow and ice were collected from the ablation area of Potanin Glacier, Mongolia. The black carbon (BC) mass concentration of surface granular ice was much larger than that of fresh snow and surface melted water, suggesting that BC is retained in the granular ice at melting. The granular ice retained BC particles best in the upstream ablation area, but the capacity decreased in the downstream ablation area.
