I think they come with the WMO header IUKN0? BABJ on the HDS feed. I
believe WMO includes this feed. I hate BUFR since there are a number of
ways to encode it. These BUFR messages have a number of subsets and
each Chinese sounding is in a subset. A given BUFR message may have a
dozen subsets.

Hello again,
We have attempted to obtain BUFR soundings via the Unidata WMO feed
with the following pqact entry:
WMO ^IU[KS]... .... ([0-3][0-9])([0-2][0-9]) FILE -close
/data/(\1:yyyy)(\1:mm)\1/(\1:yyyy)(\1:mm)\1\2.radiosonde.BUFR
However, we have been unable to locate any messages with station ID's
from China.
I was able to find this archive of global BUFR radiosonde data:
https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=gov.noaa.ncdc:C01500
and note there that it says:
"...transmitted through the National Weather Service
Telecommunications Gateway (NWSTG) in a World Meteorological
Organization (WMO) Binary Universal Form for the Representation of
meteorological data (BUFR) format beginning in May 2017."
Is the "NWSTG" different from the Unidata WMO feed available via LDM?
We are trying to understand whether we're able to locally obtain the
same data in that archive that is created from NWSTG but via LDM. Thanks!

China no longer sends data in the old text 'TEMP' format.
They only send BUFR data for soundings.

Hello,
We are requesting the "WMO" feedtype listed here:
https://www.unidata.ucar.edu/software/ldm/ldm-current/basics/feedtypes/
which seems like it should include international/global upper
air data. However, when searching for upper air data from
China specifically, I cannot locate any. I see data from Hong
Kong, Japan, Does anyone have any information as to why we
don't see anything from China? Is it in a different feedtype
or is it well known that data from China aren't routinely
found in these feeds?
Thanks in advance for any guidance anyone might have.
