IMPORTANT NOTE CONCERNING BUFR TABLE A:

WMO standard data subtypes were introduced in BUFR edition 4 to provide a mechanism for better understanding of the overall nature and content of BUFR messages exchanged between NWP centers. In contrast, local data subtypes have existed since the advent of BUFR (i.e. since edition 0) and remain available in editions 4+ for backwards-compatibility, since many NWP centers including NCEP have made extensive use of them in the past.

What is important to understand is that both values (i.e. the standard subtype and the local subtype) are intended by WMO to be supplementary to one another, and therefore both may be present in any given BUFR message when using BUFR edition 4 or later.

All local types and subtypes are shown in italics below.
