The following is metadata information for an archive of model output and code for an ice-sheet numerical model associated with the paper (henceforth PD2020): Pollard, D., and R.M. DeConto. 2020. Improvements in one-dimensional grounding-line parameterizations in an ice-sheet model with lateral variations. Geosci. Model Dev. Disc, in review, https://doi.org/10.5194/gmd-2020-131. Throughout, files 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. time = years BP (negative) or AP (positive). fort.22 are tabular ascii files with time series of overall quantities (column 1 = time, column 16 = total ice volume, last column = equivalent sea level change allowing for ice over flotation). fort.885 are tabular ascii files with time series of center-line x-axis locations of the grounding line in idealized-fjord experiments (column 1 = time, column 2 = x-axis position). The files and directories in the archive are: README_PD2020.txt ----------------- This file RunMISMIP+ (subdirectory) ------------------------- Contains subdirectories with files fort.92.nc and fort.22, for idealized fjord-like MISMIP+ experiments: Run__<1,2>_ where ctl = control, 1ra to 2rr = MISMIP+ label as in Cornford et al., The Cryo. Disc., 2020. 1 or 2 = model resolution (1 km or 2 km). v1, v2, v3 = model version with various improvements, described in PD2020. RunWAIS (subdirectory) ---------------------- Contains subdirectories with files fort.92.nc, fort.22 and fort.885 for idealized fjord-like MISMIP+ experiments: Run__ where ctl = control, fua = RCP8.5-like future climate, no hydrofracturing or cliff failure. fub = RCP8.5-like future climate, with hydrofracturing and cliff failure. v1, v2, v3 = model version as described in PD2020. Code_031420 ----------- Fortran code source (*.F) and include (*.h) files for the ice-sheet model and version number used in the paper: PSUICE3D v2. . These files are also in tar file allcode.sheetshelf_031420.tar. Make ---- make files to compile and link the model. They can use either gfortran or Intel Fortran (ifort) compilers. For the West Antarctic cases to compile and run, edits for pathnames on different machines are needed in the make files and comicepath.h, and additional Antarctic observational dataset and boundary-driving files are needed as inputs. make_eg_for_mismip+ typical MISMIP+ experiment (idealized channel) make_eg_for_wais typical West Antarctic simulation Netcdf_gfortran --------------- Netcdf library files (libnetcdf.a and netcdf.inc) used in compiling and linking, with gfortran selected in the make file. Netcdf_ifort ------------ Netcdf library files (libnetcdf.a and netcdf.inc) used in compiling and linking, with ifort selected in the make file.
