Directory contents: This dataset provides a regional multivariate oceanographic state estimate from a global ocean numerical simulation with a focus on the Southern Ocean region. The global ocean simulation is based on the MIT general circulation model (MITgcm) with Lat-Lon-Cap grid (LLC) layout and 1/48-degree (2km at equator) nominal horizontal resolution. This simulation is often referred to as LLC4320 in the community and existing publications. The simulation has 90 vertical levels, with about 1-m vertical resolution at the surface and 30 m down to 500 m, for optimized resolution of the upper-ocean processes. The ten Pre-SWOT Level-4 numerical simulation datasets produced by the NASA/JPL Jinbo Wang and Dimitris Menemenlis are hosted directly on AWS Cloud and organized by YYYY/DDD Further information on the dataset can be found here: https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_ACC_SMST_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_BassStrait_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_Boknis_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_CapeBasin_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_GotlandBasin_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_LabradorSea_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_MarmaraSea_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_NWAustralia_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_NWPacific_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_NewCaledonia_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_ROAM_MIZ_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_RockallTrough_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_WestAtlantic_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_WesternMed_v1.0 https://podaac.jpl.nasa.gov/dataset/MITgcm_LLC4320_Pre-SWOT_JPL_L4_Yongala_v1.0 Read software can be found here: https://github.com/podaac/data-readers Please send any comments or questions to podaac@podaac.jpl.nasa.gov.
