Ocean – sea ice hindcast of the Arctic with NEMO/Si3 at 12th of a degree: brittle versus viscous–plastic rheology, sea ice variables for viscous-plastic run

This 1-year long (Eulerian) twin-experiment (1997) has been performed with NEMO (OCE + SI3) version 4.2.2 at 12th of a degree of horizontal resolution and 75 levels for the 3D ocean. One experiment uses the BBM brittle rheology and the other the default aEVP viscous-plastic one. These simulations are forced with the 1-hourly near-surface atmospheric state of the ERA5 reanalysis (ECMWF). Lateral boundary conditions of the computational domain (northern North Atlantic + Arctic ocean) use monthly-averaged data of the GLORYS2v4 ocean reanalysis (CMEMS). 
See Brodeau et al 2024 (https://doi.org/10.5194/gmd-17-6051-2024) for more details about the implementation of the BBM rheology in the sea ice model SI3.
The tar file gathers monthly netcdf files that contains 3-hourly fields of sea-ice parameters, the headers are reproduced in the user manual for a complete description.
