Preface

This guide has been prepared to assist experts who wish to use the WMO Table-driven Data Representation Forms BUFR and CREX.

This guide is designed in three layers to accommodate users with different levels of requirements.


Layer 1 is a general description designed for those who need to become familiar with the table driven code forms but do not need a detailed understanding.

Layer 2 focuses on the functionality and application of BUFR and CREX, and is intended for those who must use software that encodes and/or decodes BUFR or CREX, but will not actually write the software.

Layer 1 - Basic Aspects of BUFR and CREX
and
Layer 2 - Functionality and Application of BUFR and CREX
Word   pdf

Layer 3 is intended for those who must actually write BUFR or CREX encoding and/or decoding software, although those wishing to study table driven codes in depth, will find it equally useful.

Layer 3 - Detailed Description of the Code Forms BUFR and CREX for programmers of encoder/decoder software
Word   pdf
