Ok, I see what you want here. You need to use ncml again to aggregate these 
files in the time dimension, here is a example:

<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
  <aggregation dimName="time" type="joinExisting">
    <netcdf location="file:/test/temperature/jan.nc" ncoords="31"/>
    <netcdf location="file:/test/temperature/feb.nc" ncoords="28"/>
  </aggregation>
</netcdf>

So, you can either using one ncml file to aggregate two ncml modified files, or 
you can put them together with one ncml file to do both modifying and 
aggregating funcitons. You can reference the ncml web page for more details 
information.
