NCO(1) General Commands Manual NCO(1) NAME
NCO - netCDF Operators SYNTAX
operator [ options] input-files output-file DESCRIPTION
The netCDF Operators, or NCO are a suite of programs known as operators. Each operator is a standalone, command line program which is exe- cuted at the UNIX shell-level like, e.g., ls or mkdir. The operators take netCDF (<http://www.unidata.ucar.edu/packages/netcdf>) files as input, then perform a set of operations (e.g., deriving new data, averaging, hyperslabbing, or metadata manipulation) and produce a netCDF file as output. The operators are primarily designed to aid manipulation and analysis of gridded scientific data. The single command style of NCO allows users to manipulate and analyze files interactively and with simple scripts, avoiding the overhead (and some of the power) of a higher level programming environment. The NCO User's Guide illustrates their use with examples from the field of climate mod- eling and analysis. The available operators are: ncap2, netCDF Arithmetic Processor ncatted, netCDF Attribute Editor ncbo, netCDF Binary Operator (includes ncadd, ncsubtract, ncmultiply, ncdivide) ncea, netCDF Ensemble Averager ncecat, netCDF Ensemble Concatenator ncflint, netCDF File Interpolator ncks, netCDF Kitchen Sink ncpdq, netCDF Permute Dimensions Quickly, Pack Data Quietly ncra, netCDF Record Averager ncrcat, netCDF Record Concatenator ncrename, netCDF Renamer ncwa, netCDF Weighted Averager. (Note that the "averagers" are misnamed because they perform many non-linear operations as well, e.g., total, minimum, maximum, RMS). The operators are as general as netCDF itself: there are no restrictions on the contents of the netCDF file(s) used as input. NCO's inter- nal routines are completely dynamic and impose no limit on the number or sizes of dimensions, variables, and files. NCO is designed to be used both interactively and with large batch jobs. The default operator behavior is often sufficient for everyday needs, and there are numerous command line (i.e., run-time) options, for special cases. NCO works well on all modern operating systems.

The full documentation for NCO is maintained as a Texinfo manual called the NCO User's Guide. Because NCO is mathematical in nature, the documentation includes TeX-intensive portions not viewable on character-based displays. Hence the only complete and authoritative versions of the NCO User's Guide are the PDF (recommended), DVI, and Postscript versions at <http://nco.sf.net/nco.pdf>, <http://nco.sf.net/nco.dvi>, and <http://nco.sf.net/nco.ps>, respectively. HTML and XML versions are available at <http://nco.sf.net/nco.html> and <http://nco.sf.net/nco.xml>, respectively. If the info and NCO programs are properly installed at your site, the command info nco should give you access to the complete manual, except for the TeX-intensive portions. ncap2(1), ncatted(1), ncbo(1), ncdiff(1), ncea(1), ncecat(1), ncflint(1), ncks(1), nco(1), ncpdq(1), ncra(1), ncrcat(1), ncrename(1), ncwa(1) HOMEPAGE
