| Title: | Influence of supraglacial debris on summer ablation and mass balance in the 24K Glacier, southeast Tibetan Plateau / Wei Yang, and 3 others. |
| Author(s): | Yang, Wei. |

| Abstract: | Presents observations made in summer 2008, in which mean ablation rates from 10 to 52 mm/day are strongly correlated to debris thickness. Applies simple degree-day model using synchronous observations of air temperature to calculate ablation rates, reporting maximum ablation rate and degree-day factors from middle of glacier where debris layer was about 1 cm thick. Simulations show significant effect of debris layers on summer ablation, suggesting that ablation would have been 36% higher in absence of debris. Complete covering by 65 cm-thick debris layer in ablation area would result in 59% decrease in summer ablation. Discusses how presence of debris cover changes ablation gradient in ablation zone. |
