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.)
