Initial state and surface conditions
Separate program: ce0l (ce0l stands for "création état 0 limites"). Distributed with the program gcm, compiled with the same tools For example:
makelmdz_fcm -d 144x142x79 ... ce0l
instead of:
makelmdz_fcm -d 144x142x79 ... gcm
Run ce0l with the same getin files than those you want for gcm.
ce0l creates 2 files for initial state: start.nc for the dynamics
part of gcm, startphy.nc for the physics part of gcm. ce0l creates
one file for one year of boundary conditions: limit.nc.
Cf. scripts
to see the content of limit.nc or startphy.nc.

Note that it is possible to create a file limit.nc using SST,
sea-ice fraction and land-sea mask from a coupled ocean-atmosphere,
that is NEMO-LMDZ, run. See documentation
