Version 4.6.7 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.

This document proposes an architecture for implementing thread-safe access to the netcdf-c library. Here, the term 'thread-safe' means that multiple threads can access the netcdf-c library safely (i.e. without interference or deadlock or race conditions). This does not mean that the library is itself multi-threaded. Rather, access to the library is serialized so that only one thread at a time is executing the library code.

Version 4.6.6 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 4.6.5 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.

NCAR's Computational & Information Systems Laboratory released version 6.4.0 of the NCAR Command Language (NCL) on February 28, 2017.

It appears to be the case that all current tests in the netcdf-c source tree are integration tests. That is they only access the library using calls to the externally visible API.

The DAP4 code testing is different in that it includes (for the first time) unit tests. These tests reference code that is considered internal to the library. For the library generated under autoconf, this is not a problem because those symbols are visible in the library: nothing is hidden.

Version 4.6.4 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 4.6.3 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 4.4.1.1 of the NetCDF-C library is now available. This is a maintenance release containing several important bug fixes. The Unidata netCDF team recommend migrating to netCDF 4.4.1.1 as soon as is possible to avoid a potential — albeit extremely rare — data loss issue in ncgen specific to 64-bit environments when using netCDF4 compound data types. Please read the full release announcement for details.
