29	! Added output of r_a and r_s
30	!
31	! 1551 2015-03-03 14:18:16Z maronga
32	! Added suppport for land surface model and radiation model output. In the course
33	! of this action, the limits for vertical loops have been changed (from nzb and
34	! nzt+1 to nzb_do and nzt_do, respectively in order to allow soil model output).
35	! Moreover, a new vertical grid zs was introduced.

65	! To increase the performance for parallel output, the following is done:
66	! - Update of time axis is only done by PE0
67	! - Cross sections are first stored on a local array and are written
68	! collectively to the output file by all PEs.

100	! Data output of horizontal cross-sections in netCDF format or binary format
101	! compatible to old graphic software iso2d.
102	! Attention: The position of the sectional planes is still not always computed
103	! --------- correctly. (zu is used always)!
