Instructions for the proper application of the data type designator
1. The designator specified in this table should be used to the greatest extent possible to indicate the data types of the data contained within the text of the bulletin.
2. Where the data type does not correspond exactly with the designator, the designator for the most approximate type of the data may be used.
3. The NWS will assign deginators to this table in place of the unassigned designators when needed.
