BUFRDC encoding/decoding software


ECMWF BUFRDC software is used for encoding and decoding WMO FM-94 BUFR code messages. As a part of software there are tools for conversion between BUFR and CREX .


This software is licensed under the GNU Lesser General Public License which incorporates the terms and conditions of version 3 of the GNU General Public License.


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 exhange and storage of meteorogical and oceanographic data. It is self defining, table driven and very flexible data representation system, especially for huge volumes of data.

ECMWF provide BUFR User's Guide205KB and BUFR Reference Manual 804KB that describes latest BUFR tables and ECMWF observation types and subtypes. For each subtype there is a template describing the observation.

The first version of ECMWF BUFRDC software was designed and implemented in 1987. A great deal of experience has been gathered in handling binary coded observations since then.
