45	! Description:
46	! ------------
47	! In case of extend = .FALSE.:
48	! Define all necessary dimensions, axes and variables for the different
49	! NetCDF datasets. This subroutine is called from check_open after a new
50	! dataset is created. It leaves the open NetCDF files ready to write.
51	!
52	! In case of extend = .TRUE.:
53	! Find out if dimensions and variables of an existing file match the values
54	! of the actual run. If so, get all necessary informations (ids, etc.) from
55	! this file.
56	!
57	! Parameter av can assume values 0 (non-averaged data) and 1 (time averaged
58	! data)
