COLOR CODE:
ORANGE - CONFLICT: This descriptor is associated with two or more mnemonics, depending upon the NCEP BUFR table.
PURPLE - For WMO Table B descriptors: This is awaiting validation by the WMO (last updated by the WMO 11/28/2008).
For local Table B descriptors: This will become active soon.
RED - Either: 1) This local Table B descriptor is being phased out because it is now defined as either a WMO Table B
descriptor or a different local Table B descriptor (this does not apply to local descriptors defined as Code or
Flag tables, these will always be retained); or 2) This local Table B descriptor is being phased out because it
was never actually used (it had only been proposed).
GREEN - This local Table B descriptor is being phased out because it is not, or will soon not be, found in any
NCEP BUFR tables. This does not apply to local descriptors defined as Code or Flag tables, these will
always be retained (unless the descriptor was never used).
BLUE - This WMO Table B descriptor currently has, or previously had, an incorrect attribute in NCEP BUFR tables.
GRAY - This local Table B descriptor is reserved for TDL which does not use the mnemonic-based NCEP BUFR library
interface.

"Identification of originating/generating center" (0-01-033) - OGCE are used instead to give similar information.

The modernized NWS Cooperative Observer sites can provide different variables, and on different schedules, dependent both on the type of site
(Phase I or II) and on the processing done as part of reformatting the data sent over the various communications systems in use. Here are
the primary differences:
- Phase I sites only report a single temperature observation per hour, valid at minute 0.
- Phase II GOES/HADS sites only report once per hour, but the reports contain 5-minute observations from the last hour.
