Table B2
| Explanation of Data Designators T1T2A1A2ii CCCC |
| TABLE B2 Data type designator T2 (when T1 = D, G, H, X or Y) |
| Instructions for the proper application of the data type designators |
| (1) | The designator specified in this table should be used to the greatest extent possible to indicate the type of data contained within the text of the bulletin. |
| (2) | Where more than one type is contained in the text, 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. |
