Abstract

WINDS-C (Western Indian Ocean Simulation, Climatological) is a high-resolution (1/50° in the horizontal) regional ocean simulation spanning the SW Indian Ocean under climatological forcing (1993-2018), using the Coastal and Regional Ocean Community model (CROCO). WINDS-C is forced at the lateral boundaries by a monthly climatology from the 1/12° CMEMS (Copernicus Marine Environment Monitoring Service) GLORYS12V1 global ocean reanalysis and barotropic tides from TPXO9, at the surface by a monthly climatology 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.
