PMIP4 ICE-6G-C ice-sheet data

  • nb_lat, nb_lon = 1080, 2160 (regular 10 minutes intervals)
  • latitude_values = [ -89.91667175, -89.75, -89.58334351, … 89.58333588, 89.75 , 89.91666412 ]
  • longitude_values = [ 0., 0.16666667, 0.33333334, … 359.5, 359.66668701, 359.83334351 ]
  • NO time axis (1 time step per file)
  • 48 time steps in 48 files, from 0k to 26k BP : data every 500 years from 0k to 21k BP, then every 1000 years till 26k BP
  • file names = I6_C.VM5a_10min.<time_slice>.nc
    with <time_slice> in [0, 0.5, 1, …, 20, 20.5, 21, 22, 23, 24, 25, 26]
  • all the variables for the same time step are in the same file
  • Topo: Topography (Point-value altitude), meters
    • on continents: surface altitude (including grounded ice sheet)
    • on ice-free oceans, and where there is floating ice (ice shelves): bathymetry
  • Orog: Orography (Point-value surface altitude), meters
    • on continents: altitude (including grounded ice sheet)
    • on ice-free oceans: 0.0 (zero)
    • on ice-shelves: surface altitude
  • sftlf: Point-value Landmask, %
    • values are 0 (not land) or 100 (land)
    • does not include floating ice
  • sftgif: Point-value Icemask, %
    • values are 0 (not ice) or 100 (ice)
    • floating ice is included

Notes:

  • Computing the sftlf-sftgif difference yields:
    • 100: where there is land without ice
    • -100: where there is floating ice-sheet
    • 0: elsewhere
