NAME
       ncap - netCDF Arithmetic Processor

SYNTAX
       ncap  [-3]  [-4]  [-6]  [-A] [-C] [-c] [-D dbg] [-F] [-f] [-h] [-L dfl_lvl] [-l path] [-O] [-o output-file] [-p path] [-R] [-r] [-S script-
       file][-s script][-v var[, ... ]] input-file [ output-file ]

DESCRIPTION
       ncap arithmetically processes a netCDF file.  However, in about 2008 ncap was deprecated in favor of ncap2 which far surpasses its capbili-
       ties.   ncap  will  eventually be completely removed from NCO.  It is currently retained only because it provides an easier-to-build arith-
       metic operator than ncap2.

       The processing instructions are contained either in the NCO script file fl.nco or in a sequence of command line arguments.  The options	-s
       (or long options --spt or --script) are used for in-line scripts and -S (or long options --fl_spt or --script-file) are used to provide the
       filename where (usually multiple) scripting commands are pre-stored.  ncap was written to perform arbitrary  albebraic  transformations	of
       data  and archive the results as easily as possible.  Missing values are treated correctly.  The results of the algebraic manipulations are
       called derived fields.

       Unlike the other operators, ncap does not accept a list of variables to be operated on as an argument to -v.  Rather, the -v  switch  takes
       no arguments and indicates that ncap should output only user-defined variables.	ncap does not accept or understand the -x switch.

EXAMPLES
       Compute the square of variable T
	      ncap -s "T2=T*T" in.nc out.nc

SEE ALSO
       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.
