Distinction between using IOIPSL or XIOS

How to Change Vertical and Horizontal Resolutions

To run at a different grid resolution than available initial conditions files, one needs to use the tools newstart.e and start2archive.e

For example, to create initial states at grid resolution 32×24×25 from NetCDF files start and startfi at grid resolution 64×48×32 :

  • Create file start_archive.nc with start2archive.e compiled at grid resolution 64×48×32 using old file z2sig.def used previously
  • Create files restart.nc and restartfi.nc with newstart.e compiled at grid resolution 32×24×25, using a new file z2sig.def (more details below on the choice of the z2sig.def)
