As of June 3, 2013, THREDDS Data Server (TDS) version 4.2 will no longer be in use on Unidata's servers. This is important because many of the variable names in all GRIB files have been changed in TDS 4.3. This affects almost all the model data served at Unidata.
As previously described in this
post, the Unidata Program Center's THREDDS Data Server
(TDS) using the domain name
motherlode.ucar.edu" will be upgraded to use
TDS version 4.3 at this time. Since late
March, a TDS version 4.3 server using the domain name
thredds.ucar.edu" has been in operation. The
domain name "
motherlode.ucar.edu" will not work
for TDS access after August 1, 2013. (Other
motherlode access methods will continue to work
as they currently do.)
The main changes between TDS 4.2 and 4.3 are listed here.
IDV users note: If you have not yet upgraded to IDV version 4.0 or later, you will need to do so now. The current version is IDV 4.0u1.
The timeline for transitioning from the TDS 4.2 to the 4.3 server at Unidata is as follows:
Friday, March 22nd, 2013 - the official data access URL for
the Unidata TDS changed to
thredds.ucar.edu. This address resolves to a TDS 4.3 server (the latest version).
Monday, June 3rd, 2013 - the previous
data access URL,
motherlode.ucar.edu, will be changed to use the TDS 4.3 server. This marks the end of TDS 4.2 access on Unidata systems. (Note that the changeover was originally planned for Saturday, June 1st.)
Thursday, August 1st, 2013 - the data
motherlode.ucar.eduwill no longer function. All users of the Unidata TDS should transition to using
thredds.ucar.eduby this time.
Please start changing your software now to use
thredds.ucar.edu and TDS 4.3.
