17	! Size of pf3d adjusted to the required output size (1 gridpoint less, along
18	! all three dimensions), because output of a subset of the data
19	! (pf3d(nxa:nxe...) in the NF90_PUT_VAR statement caused segmentation fault
20	! with the INTEL compiler.
21	! Subdomain data are read into temporary arrays pf_tmp/pf3d_tmp in order to
22	! avoid INTEL compiler warnings about (automatic) creation of temporary arrays
23	! Bugfix: three misplaced #endif directives

44	! Description:
45	! ------------
46	! This routine combines data of the PALM-subdomains into one file. In PALM
47	! every processor element opens its own file and writes 2D- or 3D-binary-data
48	! into it (different files are opened for xy-, xz-, yz-cross-sections and
49	! 3D-data). For plotting or analyzing these PE-data have to be collected and
50	! to be put into single files, which is done by this routine.
51	! Output format is NetCDF. Additionally, a data are output in a binary format
52	! readable by ISO2D-software (cross-sections) and by AVS (3D-data).
