Abstract Estimating the amount of glacier melt and assessing its impact on disasters and water resources are important issues. Debris, rocks covering the glacier surface, is a non-negligible factor that affects the melting speed of glaciers. In this study, we applied methods using satellite remote sensing data to estimate debriscover distribution and calculate thermal resistance over a wide area. The estimation of debris-cover distribution showed that 4.8% of global glaciers were covered with debris and the debris-covered rate varied by regions. According to the thermal resistance estimation in Central and South Asia, there were many thick debris which prevent glaciers to melt. These results suggested the importance of considering the effects of debris when estimating glacier melting, and provided basic data for broadening the analysis.
