Table C9

Instructions for the proper application of the Geographical "TILE" number designator - A two character field of the heading.

1. The designator specified in this table should be used to the greatest extent possible to indicate the geographical high resolution grid tile number of the data contained within the geographical area as specified by the grid squares defined by the producing center of the GRIB bulletin.

2. Where the geographical tile number for the area of the data does not correspond exactly with the designator, the number designator for the area most approximating that area of the data may be used. The exact area of coverage will be available within the GRIB Product Definition Section (PDS) of the bulletin.
