Description

This release contains the Matlab scripts used to generate, run and analyze the MITgcm Antarctic Slope Front (MITgcm_ASF) process-oriented simulations, as well as the configurations of the simulations. The products of MITgcm_ASF simulations and the data we used to make figures for the manuscript are available via: https://doi.org/10.15144/S4MW21

The source code of the Massachusetts Institute of Technology General Circulation Model (MITgcm) is available via: http://mitgcm.org.

Guidelines on reproducing MITgcm_ASF simulations: 

  1. Start each simulation with a 10-year integration at low resolution. Before running each simulation, you need to substitute &OBCS_PARM04 with &OBCS_PARM05 in the file input/data.obcs, and substitute &EXF_NML_05 with &EXF_NML_OBCS  in the file input/data.exf.

  2. Initialize the high-resolution simulations from the corresponding low-resolution simulations by the Matlab script higherRes.m in the folder MITgcm_ASF-csi/newexp.

  3. Each high-resolution simulation is run for a further 10 years, with a 5-year spin-up and a 5-year analysis period. Before running each simulation, you need to substitute &OBCS_PARM04 with &OBCS_PARM05 in the file input/data.obcs, substitute &EXF_NML_05 with &EXF_NML_OBCS  in the file input/data.exf. 

  4. Initialize the high-resolution production run from the corresponding high-resolution spin-up run, using the Matlab script initialize.m in the folder MITgcm_ASF-csi/newexp. When using the LAYERS package, you need to substitute numperlist = 1 with numperlist = 2 in the file code/DIAGNOSTICS_SIZE.h before running the simulations.
