HYDRODYN-SURF: HYCOM 3D-SURFmodele - zone R2000_MEDOCNORD - Data of 2025-05-28

Hydrodynamic HYCOM 3D data updated on: 04-06-2025T00:00Z

This product contains the Hydrodynamic forecasts, calculated using the HYCOM 3D model implemented by the Shom at the regional scales (Atlantic Ocean, Mediterrannnean sea).

The « Hourly surface hydrodynamics » data represent the instantaneous situation in temperature, salinity, speed and direction of currents, as hourly extracted from the surface layer of the 3D model forecasts.

Supplemental Information

Variables in the netcdf: zonal and meridional components of the current (m.s-1), salinity of sea water and in-situ Temperature (degC).

The "time" variable in the netcdf file corresponds to the date of validity (expressed in Julian days elapsed since 1 January 1950 at 00:00:00). The global attribute "bulletin_date" gives the date "T0" of the considered run.

Statement

Shom HYCOM 3D models daily run on the Météo-France calculator (Toulouse).

The HYCOM3D-SURF data available on data.shom.fr are distributed as follows: one netcdf file per day (analysis or forecast) containing 24 time intervals of all surface parameters (extraction of the first layer of the 3D model, hourly step).
