NetCDF operators (NCO) version 4.2.0

Version 4.2.0 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 notable for its improved support for "bounds" and "coordinates" attributes (often used in the CMIP5 archive), and for its native support for M$ Windows.

The minor release change in numbering of this release, from 4.1.0 to 4.2.0, was made to mark the change in NCO status to funded (by NASA) status. It also helps to alleviate some confusion between netCDF and NCO version numbering. netCDF 4.2.x just came out and it seems less confusing to call the NCO developed with it NCO 4.2.x rather than NCO 4.1.x.
