13	! Size of pf3d adjusted to the required output size (1 gridpoint less, along
14	! all three dimensions), because output of a subset of the data
15	! (pf3d(nxa:nxe...) in the NF90_PUT_VAR statement caused segmentation fault
16	! with the INTEL compiler.
17	! Subdomain data are read into temporary arrays pf_tmp/pf3d_tmp in order to
18	! avoid INTEL compiler warnings about (automatic) creation of temporary arrays

40	! Description:
41	! ------------
42	! This routine combines data of the PALM-subdomains into one file. In PALM
43	! every processor element opens its own file and writes 2D- or 3D-binary-data
44	! into it (different files are opened for xy-, xz-, yz-cross-sections and
45	! 3D-data). For plotting or analyzing these PE-data have to be collected and
46	! to be put into single files, which is done by this routine.
47	! Output format is NetCDF. Additionally, a data are output in a binary format
48	! readable by ISO2D-software (cross-sections) and by AVS (3D-data).
49	!
50	! This routine must be compiled with:
