n1850.ne30_tn14.hybrid_wavparam_vfcor_fatessp.20250205

[matsbn]

Purpose:
Hybrid run from year 29 of n1850.ne30_tn14.hybrid_wavparam_fatessp.20241226 (#68) to test impact of fix for non-negative salinity and tracer values.

The BLOM/iHAMOCC code contains all planned changes for the upcoming BLOM v1.7.1 tag (NorESMhub/BLOM#473). These are the same BLOM changes as used in n1850.ne30_tn14.hybrid_wavparam_fatessp.20241226, but with PR NorESMhub/BLOM#485 in addition. There also changes in iHAMOCC compared to n1850.ne30_tn14.hybrid_wavparam_fatessp.20241226.
