NAME


ncap2 - netCDF Arithmetic Processor, Next Generation

SYNTAX


ncap2 [-3] [-4] [-6] [-7] [-A] [--bfr sz][-C][-c][-D dbg_lvl] [-d dim,[ min][,[ max]]]
[-F] [-f] [--glb att_name= att_val]] [-h] [--hdf] [--hdr_pad sz] [-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 supercedes 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
