Mars PEM:

  • New version of scripts (launch_pem.sh and exeGCM.sh) to launch the chained simulation of GCM and PEM runs. It should be simpler and clearer for users;
  • Update of README accordingly;
  • ob_ex_lsp.asc is now in Earth years like original Laskar's data + rename obl_ecc_lsp.asc;
  • Some improvements for the script modify_startfi_orbit.sh;
  • Some changes in run_PEM.def and xml files.

1This folder contains all the files needed to run the Planetary Evolution Model (PEM).

3# launch_pem.sh:
4  Bash script file to launch the chained simulation of PEM and GCM runs.
5  The user has to specify:
6      (i)   n_earth_years -> the number of Earth years to be simulated in total;
7      (ii)  nGCM -> the number of GCM calls between PEM runs (usually nGCM=2);
8      (iii) exePEM -> the name of executable file for the PEM run;
9      (iv)  exeReshape -> the name of executable file for the data reshaping task with XIOS.
10  The path to source the arch file should be adapted to the machine.
11
12# exeGCM.sh:
13  Bash script file to run the GCM with a SLURM job. The name of the GCM executable file should be adapted. The header corresponds to the ADASTRA supercomputer and should be changed for other machines.
14
15# run_PEM.def
16  All the possible parameters to define a PEM run (read in "conf_pem.F90").
17  It needs to be included in "run_GCM.def" with "INCLUDEDEF=run_PEM.def".
18
19# obl_ecc_lsp.asc
20  File describing orbital parameters for Mars from Laskar data. It contains the Earth year and the corresponding obliquity, eccentricity and Ls of perihelion.
21
22# modify_startfi_orbit.sh:
23  Bash script file to modify orbital parameters in the file "startfi.nc" (obliquity, eccentricity, Ls perihelion and possibly initial Ls). They should be consistent with Laskar data in "obl_ecc_lsp.asc" to start the chained simulation.
24
25Note:
26  To run the chained simulation, be careful to have:
27      (i)   the xml files for XIOS. There should be "iodef.xml", "context_lmdz_physics.xml", "file_def_physics_mars.xml" and "field_def_physics_mars.xml" which can be found in the deftank folder. In "context_lmdz_physics.xml", the line for Xdiurnalave should be activated (enabled=".true.");
28      (ii)  the usual def files to run the GCM with "run.def" renamed in "run_GCM.def";
29      (iii) the "startfi.nc" file modified accordingly thanks to "modify_startfi_orbit.sh";
30      (iv)  "diagfi_PEM.def", "diagfi_GCM.def" and eventually other files...
