[ncl-talk] Fwd: Adding additional dimensions to an existing variable

[Alan Brammer]

The easiest way to do this is using the time functions and indexing.

ymdhms = cd_calendar(x, 0) ;

dec_ind = ind(ymdhms(:,1) .eq. 12) ;; find locations where month .eq. 12.

x_dec = x(dec_ind,:,:)

Adding another 2 dimensions, doesn't seem necessary. You can stack the
ind() function to be as specific or as broad as you like very easily. Will
be more flexible than multiple time dimension.
