DESCRIPTION

       ncap2  supersedes  and  is  backwards-compatible  with  ncap  which  is  now  deprecated.  Both operators
       arithmetically process netCDF files.  The primary ncap2 documentation  is  currently  the  sample  script
       <http://nco.sf.net/ncap2.in> The remainder of this manpage is identical to the ncap manpage.

       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.   ncap2  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, ncap2 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 ncap2 should  output  only  user-defined
       variables.  ncap2 does not accept or understand the -x switch.

EXAMPLES

       Compute the square of variable T
              ncap2 -s "T2=T*T" in.nc out.nc

SEE ALSO

       The full documentation for NCO is maintained as a Texinfo manual called the NCO Users 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 Users 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.
