Description

Hello helpdesk team,

My suite u-bj869 is crashing for a NEMO-related problem I can't figure out.
The suite is a copy of u-ba937 (that successfully ran in the past), the only things I have changed are:

1) In rose-edit the value of ‘rn_greenland_total_fw_flux’ (nemo_cice - namelist - NEMO namelist - Surface Boundary Conditions - Coupled Forcing)

2) The spatial pattern of the freshwater fluxes by editing directly: ecalving_v2.2x.nc
The modified file is in /work/n02/n02/vittoria/lig127k_H11/ecalving_v2.2x_new_nomask.nc
(a copy of the original one is also there: ecalving_v2.2x_original.nc )
The two files are identical, in terms of grid, time levels and etc., except for the actual field that I modified following PMIP4-CMIP6 guidelines.

The suite crashes straight away with this error (job.out):
ice_read_nc_xyz: Cannot find variable iage

Any suggestion? I can’t figure out what iage or ‘ice_read_nc_xyz’ are or why by changing the calving file this issue would arise.

Thanks,

Vittoria

Update: this problem was solved. I had forgotten to switch off the Reconfiguration and that created (I believe) a mismatch between the atmosphere and ocean input files.
