Monthly mean temperature and salinity outputs from the Southern Ocean high-resolution (SOhi) simulation

The Southern Ocean high-resolution (SOhi) is a MITgcm simulation developed to understand ocean-ice interactions along the margin of Antarctica and better quantify ocean thermal forcing on the ice shelves. SOhi is a high-resolution extension of SOSE with a longitudinal resolution of 1/24 degrees (~1.2 km at 75S) from 85.5S and telescopes to 1/12 between 40S and 30S. It has a northern boundary at the equator forced by ECCOv4r4, uses a locally improved bathymetric model from GEBCO 2020, atmospheric forcing from ERA-5, and contains thermodynamically active ice shelves. SOhi is used to understand the mechanisms of heat transport around Antarctica in order to best constrain ocean thermal forcing on the Antarctic Ice Sheet.

Methods
Monthly mean potential temperature (C) and practical salinity (psu) outputs for 12 months of SOhi simulations spanning October 2005 to September 2006 - including the ice draft and modified GEBCO 2020 bathymetry used in the SOhi simulation.
