Version 4.3.1 of the netCDF-C++ library and is now available.

Changes in the netCDF-C++ library include (but are not limited to):

• Added cmake support to distribution files created by make dist.
• Added ncFile::create(), also added a new open function and constructor to allow for more flexibility when opening a file.
• Addressed an issue reported with Intel Compilers 17.0.0.
• Updated how configure determines information about the existing netCDF-C install.
• Corrected an issue where cmake-based builds weren't generating ncxx4-config.

Version 4.7.1 of the netCDF-C library and version 4.5.0 of the netCDF-Fortran library are now available.

The Unidata Program Center's three summer student interns — Jessica Blunt from the University of Oklahoma, Max Grover from the University of Illinois, and Aodhan Sweeney from the University of Washington — have come to the end of their summer appointments. After a summer of dedicated work they presented the results of their projects to the UPC staff on July 31, 2019. You can find videos of their presentations to the UPC staff on the Unidata Seminar Series page.

This summer at Unidata I worked on expanding functionality for both the netCDF C++ library and the Python data access tool Siphon. Previously, the netCDF C++ library was lacking important functionality that was included in other netCDF libraries. Fortunately, adding this functionality is a straightforward process. I created function wrappers in the C++ library that would call previously made functions in the C library. This allows those working in a C++ framework to continue to use the netCDF libraries without sacrificing additional functionality.

Version 4.8.1 of the netCDF Operators (NCO) has been released. NCO is an Open Source package that consists of a dozen standalone, command-line programs that take netCDF files as input, then operate (e.g., derive new data, average, print, hyperslab, manipulate metadata) and output the results to screen or files in text, binary, or netCDF formats.

NetCDF has historically offered two different storage formats for the netCDF data model: files based on the original netCDF binary format, and files based on the HDF5 format. While this has proven effective in the past for traditional disk storage, it is less efficient for modern cloud-focused technologies such as those provided by Amazon S3, Microsoft Azure, IBM Cloud Object Storage, and other cloud service providers. To that end, the Unidata development team is happy to announce that we are expanding the storage solutions available through the netCDF software libraries.

Version 4.7.0 of the netCDF-C library is now available. Please read the full announcement for a list of changes. Note that new versions of the netCDF FORTRAN and C++ libraries will be available shortly.

Version 4.6.3 of the netCDF-C library is now available. Please read the full announcement for a list of changes. Note that new versions of the netCDF FORTRAN and C++ libraries will be available shortly.

Version 4.7.9 of the netCDF Operators (NCO) has been released. NCO is an Open Source package that consists of a dozen standalone, command-line programs that take netCDF files as input, then operate (e.g., derive new data, average, print, hyperslab, manipulate metadata) and output the results to screen or files in text, binary, or netCDF formats.

Version 4.7.8 of the netCDF Operators (NCO) has been released. NCO is an Open Source package that consists of a dozen standalone, command-line programs that take netCDF files as input, then operate (e.g., derive new data, average, print, hyperslab, manipulate metadata) and output the results to screen or files in text, binary, or netCDF formats.
