CLASS
25-35 WMO CODE/FLAG TABLES
ASSOCIATED WITH BUFR TABLE B
(Version
16.0.0 –
05/04/2011)
Changes awaiting validation by the WMO are in red (last updated by the WMO 05/04/2011)
(last
update of any type 02/24/2015 - not completely up to date)
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;
(b) Code
tables combining two or more existing WMO code tables to specify the
units for
an element which is defined, in the Manual
on Codes, by a group of
symbolic
letters shall be compatible with the combined code figures of the
relevant
group of symbolic letters;
(c) Code
tables combining two or more existing WMO code tables to specify the
units for
an element which is defined, in the Manual
on Codes, by different
symbolic
letters shall be compatible with the code figures of the relevant
symbolic
letters, with successive tens or hundreds values added, as different
symbolic letters
appropropriate;
(e) Reference to existing specification(s) and code table(s) in the Manual on Codes, with explanation of possible deviations, shall be given in an additional table annexed to the annexed to the code tables associated with BUFR/CREX Table B.
