TABLE B4 Data type designator T2 (when T1 = O)
Instructions for the proper application of the data type designators

(1)  The designators specified in this table should be used to the greatest extent possible to indicate the type of data contained within the body of the GRIB bulletin for oceanographic products.
(2) Where more than one data type is contained in the bulletin, the designators for only one of the data types should be used.
(3) When the table does not contain a suitable designator for the data type, an alphabetic designator which is not assigned in the table should be introduced and the WMO secretariat notified.
