Geodetic glacier-averaged mass changes in the Mt.Xixabangma area in 1974-2000 and 2000-2017 (V1.0)

Geodetic glacier-averaged mass changes in the Mt.Xixabangma area in 1974-2000 and 2000-2017 (V1.0)


The data set involved geodetic annual glacier-averaged mass balance and mass change data atMt.Xixiabangma areasin the Himalayas from 1974 to 2017. It is stored in the ESRI vector polygon format and is composed of two periods, which includes surface elevation difference between 1974-2000 (DH1974-2000, from KH-9 DEM1974 and SRTM DEM2000), surface elevation difference between 2000-2017(DH2000-2017, by DinSAR techniquesfrom SRTM DEM2000 and TSX/TDX data in 2017). KH-9 DEM is a DEM of the study area in 1974, which was generated from three scenes of optical stereo pairs from KH-9. Geodetic glacier mass change was calculated by DH above, glacier cover vector data from TPG1976/CGI2/RGI6.0 with ice density of 850 ± 60 kg m−3. The attribute data included: GLIMSId means the glacier code from GLIMS data base, Area(km2)is the glacier area by km2, area_m2 is glacier area by (m2), the glacier name, EC74_2000, the surface elevation change rate from 1974 to 2000(m a-1), EC00_2017, the surface elevation change rate from 2000 to 2017 (m a-1), MB74_2000, the geodetic glacier mass balance between 1974 and 2000(m w.e. a-1),MB00_2017, the geodetic glacier mass balance between 2000 and 2017(m w.e. a-1).MC74_2000, the geodetic glacier mass change from 1974 to 2000 (m3w.e. a-1), MC00_2017, the geodetic glacier mass change from 2000 to 2017(m3 w.e. a-1). Ut_EC74_00 is the uncertainty of glacier surface elevation change(m a-1) in 1974-2000、Ut_MB74_00, is the uncertainty of glacier mass balance for each glacier(m w.e. a-1)in 1974-2000,Ut_MC74_00, is the uncertainty of glacier mass change for each glacier(m3w.e. a-1)in 1974-2000. Ut_EC00_17,is the uncertainty of glacier surface elevation change in 2000-2017(m a-1),Ut_MB00_17,is the uncertainty of glacier mass balance for each glacier in 2000-2017(m w.e. a-1),Ut_MC00_17 is the uncertainty of glacier mass change for each glacier in 2000-2017(m3 w.e. a-1).This data set is used for the study glaciers melting and its hydrological effects in the Central Himalayas.It also could be used in studies of climatic change and disasters research in the Himalayas.
