Youll have to remove the variables that you dont want manually like this:

<netcdf xmlns='http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2'>
  <remove type='variable' name='P'/>
  <aggregation dimName='time' type='joinExisting'>
    <netcdf location='file:src/test/data/ncml/nc/jan.nc'/>
    <netcdf location='file:src/test/data/ncml/nc/feb.nc'/>
  </aggregation>
</netcdf>
