GROW-HYDRO is an archive of current speed and direction along with salinity and water temperature for global locations on a per-grid point basis. The source of GROW-HYDRO is through the Naval Research Laboratory (NRL) HYCOM Global Reanalysis. 

All variables are provided for daily means at up to 40 depths (surface to 5000 m).

Variables include: Salinity (PSU), Water Temperature (deg C), Current Speed (cm/s), Current Direction (deg to), Eastward Current Velocity (cm/s), and Northward Current Velocity (cm/s).

Standard products include time series in ASCII format.
