Re: [idvusers] [idv-developers] Changes to thredds.ucar.edu

I continue to have problems too, including with bundles that worked for a while yesterday.

Sean-
This is still not working for the GFS 80km - the bundle I use daily. thredds.ucar.edu gives no data, thredds-dev.ucar.edu is stuck at 12Z 3/31 and only the precipitation field has more than one time.
Perhaps Unidata should move back to TDS 4.3 until the issues with 4.5 are resolved.

Hi Don,

I've checked a few other collections, and from what I can tell, it's an
issue with our grib1 collections of GFS CONUS files (80km and 95km) -
other grib1 collections seem to be ok. I'm currently rebuilding the
index files to see if that will fix this particular issue. If not, I'll
pass this info along to John.

Thanks,

Sean

Hi Sean-

Me again. ;-)
It also seems that if I select a specific "file" for the GFS 80 km (e.g. 
GFS CONUS 80km 20140331 1200.grib1), I only get one time (the model run
time) and if I try to read that one time, I get an error that the IDV
couldn't get the data.  I'm trying this on thredds-dev.

Also, now my bundles don't work on thredds-dev using the server
remapping file you sent. :-(  However, if remove that and point to
thredds.ucar.edu, my 80km GFS bundle only shows one time for all fields
except the precipitation. I tried to change the data to the 6z run, but 
got the error above.

There seems to be a big incompatibility with the IDV and TDS 4.5.

Greetings!
The TDS server thredds.ucar.edu has been updated to version 4.5. Part of the move is related to security concerns raised over the past month, and part is due to the unreliability of GRIB collections to update properly 
in the old version (4.3.21). There are also several improvements and
bugfixes in 4.5.
For the IDV, this update will mostly improve access to GRIB data served 
from Unidata (no more "permission denied" issues, no more stale files,
etc.).

Bundles
=======
Bundles that use thredds.ucar.edu should not be impacted, as the urls to the latest and best time series files/collections are the same. None of 
the variable names should have changed, unless it is due to an updated
GRIB-1/2 table.

Browsing thredds.ucar.edu
=========================
You may notice a few differences in the way data are displayed. Some of them are temporary (such as datasets being listed from oldest to newest - this will be reversed asap), while others not. For example, there is a 
new dataset listed under GRIB collections called "Full Collection
(Reference / Forecast Time) Dataset". This dataset contains two time
coordinates, and allows for slicing and dicing similar to the "constant forecast offset" and "constant forecast hour" from the older, deprecated 
FMRCs. Currently, the IDV cannot take advantage of these collections,
but we hope to enable them in the near future.

If you have any questions, or run into any bugs, please contact
support-idv@xxxxxxxxxxxxxxxx or support-thredds.unidata.ucar.edu.

Cheers!

Sean
