The following is metadata information for an archive of model output and code
for an ice-sheet numerical model associated with the paper:

  Comparing Glacial-Geological Evidence and Model Predictions of Ice Sheet 
  Change since the Last Glacial Period in the Amundsen Sea Sector of Antarctica,
  by J.S. Johnson, D. Pollard, P.L. Whitehouse, S.J. Roberts, D.H. Rood, and 
  J.M. Schaefer, submitted to Journal of Geophysical Research - Earth Surface.


Model output files are named fort.<nn> and fort.<mm>.nc, as follows: 

fort.92.nc are Netcdf-format files with 2-D maps of selected
  variables at regular time intervals through a run. The main variables are:

  alatd, alond    latitudes and longitudes at grid centers.
  h               ice thickness.
  hs              surface elevation (ice, land, or ocean).
  hb              bedrock elevation.
  utop, vtop      surface ice velocities (in x,y directions
                  of the polar stereographic grid).
  maskwater       0 if grounded ice or land, 1 if floating ice or/ocean.
  alatd, alond    grid cell-center latitude, longitude, for the polar 
                  stereographic grid.
  sealev          prescribed global sea level.
  time = years BP (negative) or AP (positive).


  The 2-D variables are on a polar stereographic grid spanning West Antarctica 
  at 5 km resolution as described in the paper, and are saved at intervals 
  of 200 years from 30 ka to the present.


fort.22 are tabular ascii files with time series of overall quantities, 
  including:

  column 1 = time (years before present).
  column 16 = total ice volume. 
  last column = equivalent sea level change allowing for ice over flotation.


fort.26 are tabular ascii files with time series of elevation and thickness
  quantities at grid cells closest to the two data site locations:

  column 1 = time (years before present).
  column 2 = prescribed sea level above modern.
  column 3 = bedrock elevation, for Hudson Mountains.
  column 4 = water column thickness, for Hudson Mountains.
  column 5 = surface elevation, for Hudson Mountains.
  column 6-8 = as columns 3-5 for Mt. Murphy. 


fort.29 are tabular ascii files with time series of elevation and thickness
  quantities along the two transects in the paper, seaward along Pine Island 
  Glacier (PIG) trough, and seaward along a transect through Pope Glacier.

  column 1 = time (years before present).
  column 2 = distance along transect to grounding line, for PIG trough.
  column 3 = distance along transect to calving front, for PIG trough.
  columns 4-5 = as columns 2-3 for Pope Glacier transect.



fort.89_[PIG,POPE] are tabular ascii files defining the transects in fort.29 
  (same for each run):

  column 1 = index of grid point along transect. 
  column 2 = longitude (degrees east of Greenwich, negative = west).
  column 3 = latitude (degrees north, negative = south).
  column 4 = model polar stereographic x-value (km).
  column 5 = model polar stererographic y-value (km).
  column 6 = distance along transect (km).

This file.


Runs (directory)
----------------

Contains subdirectories A to D for each of the 4 simulations described in 
the paper (see Table 1), each containing the make file (for Intel Fortran or 
gfortran) and fort.* output files:

  A: for simulation A, with O=1,  tau=3000
  B: for simulation B, with O=10, tau=3000
  C: for simulation C, with O=1,  tau=100
  D: for simulation D, with O=10, tau=100

where O = ocean melt rate multiplier, tau = e-folding time in bedrock model 
(years).



Also contains subdirectories as above for each of the 5 simuilations in the
Supporting Information:


E. Ocean sub-ice melt factor O = 0. 
F. Bedrock relaxation e-folding time tau = 10 yr. 
G. Regional sea level rise vs. time from a separate GIA model. 
H. Basal sliding coefficient on continental shelf Cshelf = 10^-7 m yr-1 Pa-2. 
H2 (H' in paper). As H except with Cshelf = 10^-6 m yr-1 Pa-2. 


Code_102419 (directory)
-----------------------

tar file allcode.sheetshelf_102419.tar, containing all Fortran code source 
(*.F) and include (*.h) files for the ice-sheet model and version number 
(PSUICE3D v1.5) used in the paper.
