Abstract

Mountain glaciers are one of the major fresh water resources. Glacier mass balance on the Tibetan Plateau (TP) can directly reflect local climate change and plays a crucial role in the terrestrial water cycle and food security of local people. In this study, we improved the procedure to analyze Three-Line-Array (TLA) stereo images to estimate the glaciers mass balance in Kangri Karpo mountains using Zi Yuan-3 (ZY-3) TLA data and C-band Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM) in two periods, i.e. 2000-2013 and 2013-2017. The results showed that the mean mass balance of glaciers between 2000 and 2017 was -0.91 ± 0.02 m w.e. a-1. The glaciers presented accelerated mass loss in recent years (2013-2017, -2.84 ±0.05 m w.e. a-1), compared with the first decade in 21st (2000-2013, -1.59 ± 0.03 m w.e. a-1), while the melt rate in debris-covered glaciers was larger than in clean-ice glaciers.
