75	! Description:
76	! ------------
77	! This routine combines data of the PALM-subdomains into one file. In PALM
78	! every processor element opens its own file and writes 2D- or 3D-binary-data
79	! into it (different files are opened for xy-, xz-, yz-cross-sections and
80	! 3D-data). For plotting or analyzing these PE-data have to be collected and
81	! to be put into single files, which is done by this routine.
82	! Output format is NetCDF. Additionally, a data are output in a binary format
83	! readable by ISO2D-software (cross-sections) and by AVS (3D-data).
