Abstract
WINDS-M (Western Indian Ocean Simulation, Multidecadal) is a high-resolution (1/50° in the horizontal) regional ocean simulation spanning the SW Indian Ocean from 1993-2020, using the Coastal and Regional Ocean Community model (CROCO). WINDS-M is forced at the lateral boundaries by daily output from the 1/12° CMEMS (Copernicus Marine Environment Monitoring Service) GLORYS12V1 global ocean reanalysis and barotropic tides from TPXO9, at the surface hourly output from ERA5, and also includes climatological riverine fluxes. High frequency (0.5h) surface currents are provided for Lagrangian analyses, and other surface fields are provided at a daily frequency. Full 3D zonal velocity, meridional velocity, temperature, and salinity (U/V/T/S) fields are provided every 5 days.

| Data lineage: |
This dataset consists of two simulations of the Southwest Indian Ocean with high frequency surface currents. One simulation was climatological (WINDS-C) and one used realistic forcing (WINDS-M) from 1993-2020. The simulations were funded through PhD project NE/S007474/1, Marine dispersal and retention in the western Indian Ocean, held by Noam Vogt-Vincent who was supervised by Helen Johnson, both at University of Oxford. The outputs are archived on BODC's space at CEDA and assigned a CEDA DOI. No QC was done by BODC. |
