The data provided here are post-processed from the raw FESOM1.4-REcoM2 model output which can be obtained at the World Data Center for Climate (WDCC): https://www.wdc-climate.de/ui/project?acronym=HighRes_highLat_SO

The raw model output was first post-processed with MASTER_toothfish_postprocessing_AGI_save_netcdf_files_monthly_with_drift_correction.ipynb to get fields of in-situ temperature (t_insitu) and partial pressure of oxygen (pO2) on the regular grid used in this study (see Mesh_ancillary_information_v20220919.nc).

Subsequently, these data are post-processed with reduce_depth_levels_drift_corr_files.sh.
