The NSF Unidata THREDDS development team is happy to announce the release of version 5.11.0 of the netCDF-Java/Common Data Model (CDM) library. This release contains a number of enhancements, bug fixes, and 3rd party dependency updates. New features include support GRIB-2 template 3.33 and RRFS aerosol product support, upgrades to NCEP GRIB2 tables, and improving xpublish DAP2 compatibility.

Version 5.4.0 of the netCDF Operators (NCO) has been released. Some notable features include:

• All operators allow setting the netCDF4 metadata block size. 
• Many operators now optionally preserve orphaned dimensions. 
• ncclimo can now climatologize simulation ensembles. 
• ncremap tolerates absent hybrid p0/P0 variables. 

Users interested in these features should upgrade to 5.4.0.

The NSF Unidata THREDDS development team is happy to announce the release of version 5.10.0 of the netCDF-Java/Common Data Model (CDM) library. This release contains a number of enhancements, bug fixes, and 3rd party dependency updates. New features include support for Blosc compression, object storage support for feature collections (primarily focused on GRIB), and the generation of Software Bill of Materials (SBOMs) for uber-jars (e.g., netcdfAll, ncIdv, toolsUI) using the CycloneDX standard.

Version 5.3.9 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 5.3.8 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.

The Unidata netCDF team is happy to announce the availability of netCDF 4.10.0 C library.

Version 5.3.6 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 5.3.5 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.

The netCDF-Java 5.9.1 release had an issue where the toolsUI jar was missing a critical properties file, preventing the application from launching. This has been fixed in a new toolsUI-only release, v5.9.1.1, available on the NSF Unidata netCDF-Java downloads page and GitHub. Additionally, netCDF-Java command-line utilities and toolsUI are now available via conda-forge thanks to community efforts!

The NSF Unidata THREDDS development team is happy to announce the release of version 5.9.1 of the netCDF-Java/Common Data Model (CDM) library. This release contains a number of bug fixes for user reported problems, including a major bug that can be triggered in multithreaded environments.
