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

May I chime in. Like Don, but using McIDAS-V, I have bundles that continuously update and they stopped updating on Frinday.

Hi Sean-
My bundles that access grids from thredds.ucar.edu no longer seem to work after this change. For example, this bundle:
http://www.esrl.noaa.gov/psd/repository/entry/get/gfs80km.xidv?entryid=8ed2cb87-762c-4bf2-af7e-1ef959db2b11 

gives no error, but loads no data.  My Boulder bundle:
http://www.esrl.noaa.gov/psd/repository/entry/get/boulderweather.xidv?entryid=b569207d-8470-4054-9605-d7ebb227810b 

gives an error (submitted support-idv request).
I have bundles that continuously update and they stopped updating on Frinday.

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
