Reminder: Unidata's Motherlode THREDDS Data Server is being Phased Out

As previously described in this post, the Unidata Program Center's primary THREDDS Data Server (TDS), currently using the domain name "motherlode.ucar.edu" is being phased out in favor of the new domain name "thredds.ucar.edu". The domain name "motherlode.ucar.edu" will not work for TDS access after August 1, 2013.

UPDATE: Please note that this change affects connections to the THREDDS Data Server only. Other services provided by motherlode.ucar.edu will remain in operation until further notice.

Use of TDS version 4.2 on the Unidata TDS server is also being phased out, and will not be available after June 1, 2013. 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. The Program Center is developing an application that will allow you to determine the new variable names (in NCEP model datasets) given the old names.

The main changes between TDS 4.2 and 4.3 are listed here:

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).
• Saturday, June 1st, 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.
• Thursday, August 1st, 2013 - the data access URL motherlode.ucar.edu will no longer provide THREDDS Data Services. All users of the Unidata TDS should transition to using thredds.ucar.edu by this time.

Please start changing your software now to use thredds.ucar.edu and TDS 4.3.
