    To better understand fluctuations and their mechanisms of large glaciers in high mountain Asia, we conducted in-situ observations in the Nepal and Bhutan Himalayas with analyses of remotely sensed satellite data and of numerical modelling. We developed a numerical model for debris-covered glaciers, in which distribution of debris thermal resistance was estimated with remotely sensed data as a proxy of debris thickness, and then ice melting was calculated by considering heat balance. By analyzing high resolution remotely sensed satellite data, we revealed mass changes in a couple of Himalayan glaciers. In addition, we compiled glacier inventory covering high mountain Asia, and then revealed areal changes in glaciers in the eastern Himalayas. We also revealed that debris-cover extent was highly correlated with upper glacier-free slope facing southwest at which diurnal freeze-thaw cycle could produce and supply debris material on glacier.
