Instructions for the proper application of level designator.
1. The designator specified in this table should be used to the greatest extent possible to indicate the levels below the ocean surface in the body of the GRIB bulletin for oceanographic products.
2. When the table does not contain a suitable designator for the level, a designator which is not assigned in the table should be used.
