Increased Mass Loss of Glaciers in the Sawir Mountains of Central Asia between 1959 and 2021

Glacier mass balance can be regarded as a major direct index of climate variations. In this paper, geodetic method was used to evaluate the Sawir glaciers based on topographic map DEM (Digital Elevation Model), SRTM 30 m DEM, ASTER and Sentinel-1 Synthetic Aperture Radar 10 between 1959–2021, in order explore response climatic alterations. case Muz Taw glacier, first comprehensive dataset concerning mass-balance readings for 2014–2021 period provided eight-year consecutive field measurements. The glaciological average reached –883.4 ± 130 mm a–1 during period. all Mountain range ?0.43 0.12 w. e. a?1 1959 2000, accelerated ?0.56 0.13 2000 2021. A comparison measurements remote-sensing approaches determining glacier’s proves feasibility approach, which involves monitoring DEMdata. addition, our findings support contention that air temperature is dominant factor glacier loss surface elevation change.
