[210]	6	! Size of pf3d adjusted to the required output size (1 gridpoint less, along
	7	! all three dimensions), because output of a subset of the data
	8	! (pf3d(nxa:nxe...) in the NF90_PUT_VAR statement caused segmentation fault
	9	! with the INTEL compiler.
[191]	10	! Subdomain data are read into temporary arrays pf_tmp/pf3d_tmp in order to
	11	! avoid INTEL compiler warnings about (automatic) creation of temporary arrays
[179]	12	! Bugfix: three misplaced #endif directives

	37	! Description:
	38	! ------------
	39	! This routine combines data of the PALM-subdomains into one file. In PALM
	40	! every processor element opens its own file and writes 2D- or 3D-binary-data
	41	! into it (different files are opened for xy-, xz-, yz-cross-sections and
	42	! 3D-data). For plotting or analyzing these PE-data have to be collected and
	43	! to be put into single files, which is done by this routine.
	44	! Output format is NetCDF. Additionally, a data are output in a binary format
	45	! readable by ISO2D-software (cross-sections) and by AVS (3D-data).
	46	!
	47	! This routine must be compiled with:
