The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.3.18 were released on August 1, 2013. The development team recommends this upgrade for anyone using the CDM or TDS.
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.3.17 were released on June 7, 2013. The development team recommends this upgrade for anyone using the CDM or TDS.
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.)
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.
A new stable release of the NetCDF-Java/Common Data Model (CDM) library and the THREDDS Data Server (TDS), version 4.3.15, is now available on the NetCDF Java Library download page and the THREDDS Data Server page. We recommend that you upgrade to the current stable version as soon as possible in all cases.
The NetCDF-Java/Common Data Model (CDM) library version 4.3.14 was released on November 20, 2012. Version 4.3 includes a complete rewrite of GRIB1 and GRIB2 file handling as well as a number of other features.
The UCAR Research Applications Laboratory (RAL) has released Nujan version 1.4.1. Nujan is a pure Java writer for HDF5 and NetCDF4 files. Nujan is 100% open source and is released under the MIT license. Nujan is intended to be useful in situations where portability and a simplified development process are more important than access to the complete HDF5 feature set.
As part of Unidata's ongoing commitment to community driven software, and to make collaborative development easier and more transparent, we have moved the THREDDS and NetCDF-Java/Common Data Model (CDM) source repository to the GitHub "social coding" site. See the full article for details.
