Hi Robb,
My responses are interspersed below...

Jeff,
I have some questions about bufr tables. Hope you can answer these.
A snippet of your code shows:
C
IF ( cborg (1:4) .eq. 'KARP' ) THEN
bfstyp = 'NC004004'
ELSE IF ( cborg (1:4) .eq. 'EGRR' ) THEN
bfstyp = 'NC004006'
ELSE
bfstyp = 'NC004009'
END IF
It appears that you are using part of the product pattern to load
certain tables, is that correct?
Actually, the pattern is being used to select the data subtype (either
006 or 009). Both of these subtypes are defined in the same BUFR tables
file, which is permissible and which allows the code to only have to
read in a single tables file.
In doc:
http://www.nco.ncep.noaa.gov/sib/decoders/BUFRLIB/toc/dfbftab/
it mentions that the mnemonic tables need to be loaded according to
datatype and data subtype. This seems different then your code, can
you explain this?
The tables do need to be loaded according to data type and subtype,
meaning that you do always need to ensure that the types and subtypes
you are working with are defined in the table(s) you have loaded. But
again, there is nothing preventing a single tables file from containing
more than one, or indeed even all of the subtypes in question, which
makes the overall code design much simpler.
In doc:
http://www.emc.ncep.noaa.gov/mmb/data_processing/NCEP_BUFR_File_Structure.htm#ASCII_Table
it mentions that the first descriptors in the data refer to what
tables need to be loaded to decode. How many products follow this syntax?
I'm not sure I understand this question - can you point me to the exact
text which you are referring to in the above document?
In doc:
http://www.emc.ncep.noaa.gov/mmb/data_processing/bufrtab_tabled.htm
In the local classes there are many reference to mnemonic tables that
I can't find anywhere on the web. The tables are in [] similar to
[NC003003]. Where can I download these tables?
Go to http://www.nco.ncep.noaa.gov/pmb/codes/nwprod/fix/ where you'll
see a listing of all of our current BUFR tables. In particular, the
definition of NC003003 would be in bufrtab.003, along with the
definitions for all of the other data which have type 003.
Thanks,
RObb...

Dear Robb,
We noticed that you recently asked to join our "BUFRLIB support"
mailing list. However, this is a list for use by myself and all of
the other folks who collectively maintain the NCEP BUFRLIB software -
we use it to receive user inquiries, discuss maintenance issues,
respond to bug reports, etc. I believe you would be better served by
instead subscribing to our "BUFRLIB announce" mailing list at
address@hidden This is the list we
use to notify our users of general announcements, software updates,
etc. You can still post inquiries to the "BUFRLIB support" list, but
it's not a list to which you should be directly subscribing.
Best regards,
-Jeff
