       ncap2 - netCDF Arithmetic Processor, Next Generation

SYNTAX

       ncap2  [-3]  [-4] [-5] [-6] [-7] [-A] [--bfr sz_byt][-C][-c][-D dbg_lvl] [-d dim,[ min][,[
       max]]] [-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][-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

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

       portions  not  viewable  on  character-based  displays.   Hence  the  only  complete   and
