Hi,

I suggest installing the NCO (netCDF Operators) software, available from
sourceforge, and described here:

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

In particular, the operators ncrcat and ncecat are designed for merging
netCDF data.  Also, if you're merging the files before computing averages,
NCO provides averaging operators that compute the averages without merging
first, for example ncra.

Other software that provides similar capabilities includes NCL and CDO:
