Abstract: Glacier mass balance is among the clearest natural indicators of ongoing climate change and is important for the assessment of water resources and sea-level rise. However, there are few glaciers in southeastern Tibetan Plateau, where continued mass balance measurement exists. In addition, debris cover is widely present in glacier ablation areas in southeastern Tibetan Plateau, which influences glacier mass balance and response to climate change by affecting the melt rate of the underlying ice. Accordingly, overall characteristics of glacier mass balance in this region are not yet clear. Glacier mass balance of Hailuogou catchment, located in the east side of Mount Gongga, southeastern Tibetan Plateau, is reconstructed for the period 1952-2009 by an energy-mass balance model that accounts for the significance of debris cover and its effect on the ice melt rate, forced by observed meteorological data and gridded climate data. These data are stored in TXT format. A comparison between simulations and observed ablation and river runoff in the catchment validates the model performance. This dataset includes mass balance data and equilibrium line altitude data, which can reflect overall variation in glacier mass change in the Hailuogou catchment for the period 1952-2009. Therefore, this dataset can be used as the basic data for studying glacier change and its response to climate change in the maritime glacierized region of the southeastern Tibetan Plateau.
