Notes: In developing code tables associated with BUFR/CREX Table B to specify units of elements, the following principles should be applied: (a) Code tables specifying the units for an element which is defined, in the Manual on Codes, by a single symbolic letter shall be compatible with the relevant existing WMO code tables; Overview of WMO Technical Guidance Documentation (documentation status: 15 May 2006) This document provides a list of technical guidance documentation to be used by Members. At its first session (Geneva, 25-27 April 2006), the Inter-Commission Task Team on Quality Management Framework (ICTT-QMF) decided to produce a list of the Commission 2005. The RO specification was published in WMO BUFR tables from Version 12 ([RD.4]), and ap-proved for use on the GTS from November 2005. This document is intended for users wishing to encode or decode RO data. Whilst all of the information to do this is available in the published WMO manuals and extracted tables (downloadable from the Guide to WMO Table Driven Code Forms: FM 94 BUFR . and . FM 95 CREX . Layer 1: Basic Aspects of BUFR and CREX and. Layer 2: Layout, Functionality and Application of BUFR and CREX Geneva, 1 January 2002 . Preface . This guide has been prepared to assist experts who wish to use the WMO Table Driven Data Representation Forms BUFR and CREX. The WMO FM-94 BUFR, Binary Universal Form for the Representation of Meteorological data, is a binary code designed to represent, employing a continuous binary stream, any meteorological data.It has been designed to achieve efficient exchange and storage of meteorological and oceanographic data. It is self defining, table driven and very flexible data representation system, especially for huge Standard Identifier. FM 94-X Ext. BUFR WMO No. 306 . Title of Standard.
