[ncl-talk] append array

[Rashed Mahmood]

This can be done in many ways, e.g.:

*method1*: (using function *dim_pad_extend:
https://www.ncl.ucar.edu/Document/Functions/Shea_util/dim_pad_extend.shtml
<https://www.ncl.ucar.edu/Document/Functions/Shea_util/dim_pad_extend.shtml>*
):

  nlev_X1 = 25
  nlev_X2 = 19
  nlev_tot = nlev_X1+nlev_X2
  nExt       = nlev_X2

  X1 := dim_pad_extend(X1,nExt,1,False)  ; note the reassignment operator *":";
this would extend the dimension of X1 by nExt.*

  X1(:,nlev_X1:nlev_tot-1,:,:)  = X2


*method 2:*
 Rearrange the dimensions (see
https://www.ncl.ucar.edu/Document/Language/reorder.shtml) and use the
function *array_append_record*.
