Pre-SWOT Level-4 Hourly MITgcm LLC4320 Native 1/48-degree Grid Oceanographic Version 1.0 Datasets Release
PO.DAAC is pleased to announce the public release of the Pre-SWOT Level-4 numerical simulation datasets Version 1.0. These datasets contain hourly model outputs subsetted from a global ocean simulation using the MITgeneral circulation model (MITgcm) on a 1/48-degree nominal Lat/Lon-Cap horizontal grid (namely, LLC4320). The MITgcm LLC4320 is a forward simulation progressively spun up from lower resolution products of the Estimating the Circulation & Climate of the Ocean (ECCO) project forced by ECMWF 6-hourly wind and barotropic tides. It has been used in studying global ocean submesoscale (10-50 km) dynamics (e.g., Rocha et al., 2016; Su et al., 2019, Qiu et al., 2019), baroclinic tides (e.g., Savage et al., 2017, Arbic et al., 2018) and SWOT mission support (e.g., Wang et al., 2018). A global model-observation comparison can be found....
