The dissemination
supports products which can be represented as fields of values of
single parameters over a defined area. The data are represented in
FM 92 GRIB code, and the optional bitmap section of GRIB is used to
designate the land-sea mask, indicating which points are present
and which are missing with respect to the total area. Also, data is
available in the form of rectangular "hollow boxes" to provide
boundary conditions for limited area models.Member States may also
specify bitmaps of required points.
Data are available at
any multiple of the basic grid of the generating model and for any
user-defined sub-area.
A number of products
are available in the field form. Products can be grouped into the
following categories:
- Control, perturbed
and calibration/validation forecast products
- Event probability
