Version 4.4.4 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.
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.
From the release message:
This release is mainly a bugfix and stability release.
A few new features improve some corner-cases:
It includes workarounds that allow NCO to successfully work with
some names that violate netCDF but not HDF rules.
Users can now retain "orphaned" dimensions after variable subsetting.
nces now works with hyperslabs that resolve to the same size.
Group broadcasting by
ncbo is more intelligent when differencing
ensemble means (created by
nces) from full datasets.
A potentially serious bug in
ncwa --mask_condition has been fixed.
ncwa --mask_condition are encouraged to upgrade.
Additional details are available in the ChangeLog.
