Hi Leilei :
I have made a new release that hopefully will work, find it at the same place.
It will have version 3.3.05.
Im not sure how you are installing, but its a good idea to delete the expanded
webapp/thredds directory to be sure you get the new stuff.

Hi Leilei,
I grabbed the file mentioned below from your ftp site. Robb tried it
out and could read it fine (and a few others I got from there).
We are not using TDS 3.2 on motherlode. We are using the code from our
development (currently 3.3) branch. We're guessing there is a bug fix
on that branch that didn't get into 3.2. If you are interested in
trying that version, I can send you the thredds.war file. Since it
isn't a stable release yet, we don't advise relying on it but it
should be fine for testing and such.
Let me know if you want the 3.3 thredds.war file.

Seems it is an unfortunate day for me.
I've reloaded correct GRIB-2 NDFD data files onto our TDS. Metadata
seems fine with Netcdf Tool UI. But on "DODS Dataset Access Form",
when I try to get ascii for a subset of some variables, I've got an
error. I'm using latest official thredds.war 3.2 and even
reinstalled tomcat with the version you suggested, still got no luck.
Part of related error msg is followed. Seems array index is out of
bound. I remember we got similar problem back to Aug and you've fixed
it for other data. Weirdest thing is same data file(downloaded one
NDFD file from your site)works on your motherlode while not working
on our TDS. Are you using v3.2 with your motherlode thredds?

Interesting. I wonder what is different about them. Can you send us

Seems it can't be opened at all and Netcdf Tool verified this too.
Yes, GRIB-2 data files directly downloaded from NDFD work fine in
TDS. But the files I've got problem are from NCDC archive system.
I'm puzzled because these files seem in GRIB-1 format when I use
'degrib' decoder to decode them. And current 'degrib' can't handle
them too because center & subcenter are not included in local use
tables.
Thanks,

Hi Leilei,
The GRIB data is being read by the netCDF-java 2.2 library which
has a number of adapters for reading various file formats. I'm
CCing Robb Kambic who developed and maintains our GRIB code. I
just checked on our server and looks like we are serving NDFD
data. Here's the catalog for the NDFD data we're serving in case
you want to take a look at that
http://motherlode.ucar.edu:8080/thredds/idd/model/NDFD/CONUS_5km/catalog.xml
Are you getting any relavent messages in the TDS logs in the
${TOMCAT_HOME}/content/thredds/logs directory?
Another thing you could do is use the netCDF Tools UI to look at
one of your data files and see if it can read it in. In the
"Viewer" tab you can click on the folder icon to find a local file
and try to open onf the your NDFD files. That way we'll know if it
is a TDS or nc/GRIB issue. If the ToolsUI can't open the file, can
you make one available so Robb can take a closer look?
Let us know what kind of error messages (if any) you get from the
ToolsUI or in the TDS logs.
Thanks,
Ethan

Hi Ethan:
Which decoder does TDS use to decode GRIB files? Is it degrib?
We're trying to serve NCDC archived NDFD data files through TDS
which in GRIB but failed.
