Three-level Modelling of WMO data products based on BUFR/CREX tables

Model of the WMO data product: TM 307080 – Synoptic reports from fixed land stations suitable for SYNOP data

1. The model is defined as an instance of the meta-model as follows:

1.1 A table that is an instance of the meta-model of the table of the tables of the tree

1.2 Tables that are instances of the meta-model of the tables of the tree

The documents describing the structure and the contents of these tables and constituting the basic reference documentation of the model are given in Annexes 1 1

and 2.

2. The diagram showing the tables of the tree with their fields and their relationship is given in Annex 3.

1 The contents of the column alias_2 of the tables in Annex 1 are derived from the column description when available and were entered manually.
