The dissemination supports products which can be represented as fields of values of a single parameter over a defined area. The data are represented in FM 92 GRIB code.

A number of products are available. Products can be grouped into the following categories:

Raw atmospheric data
Raw atmospheric hindcast data
Raw wave data
Raw wave hindcast data
Real-time weekly means
Hindcast weekly means
Wave real-time weekly means
Wave hindcast weekly means
Anomaly weekly means

Horizontal resolution:

- 0.25° x 0.25° latitude-longitude grid for days 1 to 10 ( leg1)

- 0.5° x 0.5° latitude-longitude grid for days 10 to 32 (leg 2 and leg3)

- the Gaussian grid appropriate to the forecast model in use. The following Gaussian grid numbers are supported: 320,200 (for leg1) 160, 128, 80, 48 and 32. (for leg 2 and 3)

- any sub-area

Vertical resolution

- pressure levels (depending on the specific parameter and the forecast time step): 1000, 925, 850, 700, 500, 400, 300, 200, 100, 50, 10 hPa

- no model level data are generated;

Verifying times for real-time data and indicts

- Atmospheric data T+0 to T+768 (inclusive) at 6, 12 or 24 hour intervals depending on a parameter;

- Wave data T+0 to T+768 (inclusive) on 24 hour intervals

Verifying times for weekly means and hindcast weekly means

- Forecast time steps ranges 96-264, 264-432, 432-600 and 600-768

Monthly Forecast products are disseminated as one file per forecast day (all forecast time steps falling within a day are in the same file). Please, note that 00 hours is considered as the first hour of the day.

A four sets of dissemination files are generated by the Monthly Forecasting system each set containing the following data:

1. Real-time atmospheric data, real-time weekly means and anomaly means (data stream ENFO)

2. Hindcast atmospheric data and hindcast weekly means (data streams ENFH and EFHS)

3. Real-time wave data and real-time weekly means (data stream WAEF)

4. Hindcast wave data and hindcast weekly means (data stream ENWH)
