NAME

       ncap2 - netCDF Arithmetic Processor, Next Generation

SYNTAX

       ncap2 [-3] [-4] [-5] [-6] [-7] [-A] [--bfr sz_byt][-C][-c][-D dbg_lvl] [-F] [--fl_fmt=fmt]
       [-f] [--glb att_name= att_val]] [-h]  [--hdf]  [--hdr_pad  sz_byt][--hpss_try]  [-l  path]
       [--no_tmp_fl]  [-O]  [-o  output-file] [-p path] [-R] [-r] [--ram_all] [-S script-file][-s
       script][-t thr_nbr][--uio][-v var[,...]]  [ input-file ] output-file

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

       If the info and NCO programs are properly installed at your site, the command

       should give you access to the complete manual, except for the TeX-intensive portions.
