ECMWF 40 Year Re-analysis (ERA- 40) Global Wave Forecast Data Set



 

 
  Please use our Online Ordering system to order this data set.

Description:

  • a subset of fields are available from forecasts with base times 0600 and 1800 UTC each day for forecast steps 3 and 6;
  • a full set of fields are available from forecasts from with base times 0000 and 1200 UTC have each day for forecast steps 3, 6, 12, 18, 24, 30 and 36;
  • each parameter is stored as a field of grid point values at 1.5 degree resolution.

Fields available from base times 0000 and 1200 UTC are:

10 metre wind speed, 2-D wave spectra, coefficient of drag with waves, mean direction of total swell, mean direction of wind waves, mean period of total swell, mean period of wind waves, mean square slope of waves, mean wave direction, mean wave period, mean wave period based on first moment, mean wave period basd on first moment for swell, mean wave period based on first moment for wind waves, mean wave period based on second moment, mean wave period based on second moment for swell, mean wave period based on second moment for wind waves, peak period of 1D spectra, significant height of total swell, significant height of wind waves, significant wave height, wave spectral directional width, wave spectral directional width for swell, wave spectral directional width for wind waves.

Other fields available are:

10 metre wind, coefficient of drag with waves, mean wave direction, mean wave period, peak period of 1D spectra, significant wave height are available from base times 0600 and 1800 UTC also;


2-D wave spectra are available for 12 directions and 25 frequencies at step 3 from base times 0000, 0600, 1200 and 1800 UTC.

Missing data:

No forecast data was archived for the period 1989-01-01 to 1991-12-14;


Additionally, forecast data from base times 0600 and 1800 UTC was not archived for the periods 1957-12-01 to 1960-11-28 and 1991-12-15 to 1993-06-20.
