[210]	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

	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).
