#### Description

Static bathymetry for the Global Ocean Waves Analysis and Forecast
system. This dataset provides the sea floor depth in meters.

The global wave system of Meteo-France is based on the wave model
MFWAM which is a third generation wave model. MFWAM uses the
computing code ECWAM-IFS-38R2 with dissipation terms developed by
Ardhuin et al. (2010). The model MFWAM was upgraded on November 2014
thanks to improvements obtained from the European research project
'my wave' (Janssen et al. 2014).

The model mean bathymetry is generated by using 2-minute gridded
global topography data ETOPO2/NOAA. Native model grid is irregular
with decreasing distance in the latitudinal direction close to the
poles. At the equator the distance in the latitudinal direction is
more or less fixed with grid size 1/10 degrees. The operational
model MFWAM is driven by 6-hourly analysis and 3-hourly forecasted
winds from the IFS-ECMWF atmospheric system. The wave spectrum is
discretized in 24 directions and 30 frequencies starting from 0.035
Hz to 0.58 Hz. The model MFWAM uses the assimilation of altimeters
with a time step of 6 hours. The global wave system provides
analysis 4 times a day, and a forecast of 10 days at 0:00 UTC. The
wave model MFWAM uses the partitioning to split the swell spectrum in
primary and secondary swells.

GLOBAL_ANALYSISFORECAST_WAV_001_027, implemented by Mercator Ocean
International. It provides a comprehensive overview of the global
ocean wave analysis and forecasting system produced by Meteo-France.
The system delivers aggregated analyses and a 10-day forecast,
updated twice-daily, including various integrated wave parameters
such as significant wave height, period, direction, and Stokes drift
for both the total wave spectrum and partitioned waves (wind wave,
primary and secondary swell).
