48	! of this action, the limits for vertical loops have been changed (from nzb and
49	! nzt+1 to nzb_do and nzt_do, respectively in order to allow soil model output).
50	! Moreover, a new vertical grid zs was introduced.

80	! To increase the performance for parallel output, the following is done:
81	! - Update of time axis is only done by PE0
