Hi Luis,

Probably the easiest way is to use the NCO package of netCDF utility programs:

  http://www.unidata.ucar.edu/netcdf/software.html#NCO

and specifically the "ncap2" program.  This utility program supports arithmetic
on input netCDF files to produce a new netCDF output file.  Documentation for
ncap2 is here:

  http://nco.sourceforge.net/nco.html#index-ncap2-725

Check the examples for similar uses.
