Version 4.4.6 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.

The NCO project is coordinated by Professor Charlie Zender of the Department of Earth System Science, University of California, Irvine. More information about the project, along with binary and source downloads, are available on the SourceForge project page.

Version 4.4.5 of the netCDF Operators (NCO) has been released.

From the release message:

This release is mainly a bugfix and stability release. A few new features improve some corner-cases: NCO now supports longer lists of input files, DAP files on HTTPS servers, and the CF ancillary_variables convention.

Version 4.4.0 of the netCDF-Fortran library is now available.

Some highlights of the 4.4.0 release:

• For 32-bit platforms fixed integer fill parameters, initialized potentially unitialized variables, and provided some missing defaults (Thanks to R. Weed).
• Fixed CMake builds on 32-bit platforms.
• Added new inq_path and rename_grps functions analogous to corresponding C functions. Added associated tests. (Thanks to R. Weed)
• Added support for NF_MPIIO, NF_MPIPOSIX, NF_PNETCDF flags and NF_FILL_UINT. (Thanks to R. Weed)
• Fixed potential bug in attribute functions for integer values when Fortran INTEGER*1 or INTEGER*2 types are the same size as C long. (Thanks to R. Weed)
• Added test for compiler support of Fortran 2008 ISO_FORTRAN_ENV additions and TS29113 standard extension.
• Fixed C_PTR_DIFF_T issue reported by Orion Poplowski. (Thanks to R. Weed)

Version 4.3.2 of the NetCDF-C library is now available.

Some highlights of the 4.3.2 release:

• Improved type handling with respect to fill-values.
• Enabled netCDF-4 bit-for-bit reproducibility for nccopy and other applications (thanks to Rimvydas Jasinskas and Quincey Koziol).
• Improved cmake build process.
• As part of an ongoing project, the Doxygen-generated netCDF documentation has been reorganized. The goal is to make the documentation easier to parse, and to eliminate redundant material.

Detailed information about the release is available in the Release Notes.
