Results for 'Health and sustainability of glaciers in High Mountain Asia'

  • 1. Swiss Federal Research Institute WSL
  • 2. VAW, ETH Zurich

Description

Contains 1 .csv file including the glacier health metrics used in Miles and others (2021) for all RGI glacier outlines larger than 2km2 in High Mountain Asia (regions 13/14/15). 

Also contains 1 .zip file with principal regridded inputs and results for continuity-derived glacier specific mass balances of High Mountain Asia, 2000-2016. A subdirectory contains the following for each glacier, identified by its Randolph Glacier Inventory identification number (RGIID), all in geotiff format and at the same resolution:

  • '*_AW3D.tif': regridded digital elevation model based on the ASTER GDEM3 (apologies for misleading name)
  • '*_debris.tif': binary rasterized debris-cover map based on the results of Scherler et al (2018)
  • '*_dH.tif': regridded elevation change rate from Brun et al (2017), in m per year
  • '*_dHe.tif': regridded elevation change rate uncertainty from Brun et al (2017), in m per year
  • '*_FDIV.tif': raster of flux divergence, in m per year
  • '*_FDIVe.tif': raster of flux divergence uncertainty, in m per year
  • '*_Hdensity.tif': raster of estimated density of dH signal, in 1000 kg per m3
  • '*_SMB.tif': raster of specific mass balance, in m w.e. per year
  • '*_SMBe.tif': raster of specific mass balance uncertainty, in m w.e. per year
  • '*_Smean.tif': raster of column-average surface speed based on regridded data from ITS_LIVE (Gardner et al, 2019), in m per year
  • '*_THX.tif': raster of glacier thickness from consensus estimate of Farinotti et al (2019), in m 
  • '*_zFDIV.tif': raster of zonally-aggregated flux divergence, in m per year
  • '*_zFDIVe.tif': raster of zonally-aggregated flux divergence uncertainty, in m per year
  • '*_zones.tif': raster of elevation-based zonal segmentation for each glacier
  • '*_zSMB.tif': raster of zonally-aggregated specific mass balance, in m w.e. per year
  • '*_zSMBe.tif': raster of zonally-aggregated specific mass balance uncertainty, in m w.e. per year
