Version 4.9.5 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 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:
Version 4.9.5 is a minor NCO release that contains a few new features and fixes to more smoothly work with current and future releases of the E3SM climate model and with the next netCDF release. Unless the features/fixes listed below affect you, chillax and upgrade next time.
ncclimosupports alternates to "area" and "ncol" as names for the area field and the horizontal dimension that it assumes for computing global average means from splitter output with the
--glb_avgoption, and for creating CMIP6-like timeseries that automatically include the area variable. Two new options,
--hrz_dmn, control the name of the area variable (default is "area") and of the horizontal dimension(s) (default="ncol") over which to average the splitter output when invoked with
--glb_avg. For alternate names invoke with, e.g.,
ncclimo --glb_avg --area=area_p ... ncclimo --glb_avg --area=area_d --hrz_dmn=ncol_d ... ncclimo --glb_avg --hrz_dmn=lat,lon ...In all cases the splitter will output the correct area variable.
Additional details are available in the ChangeLog.
