90	! Description:
91	! ------------
92	! In case of extend = .FALSE.:
93	! Define all necessary dimensions, axes and variables for the different
94	! netCDF datasets. This subroutine is called from check_open after a new
95	! dataset is created. It leaves the open netCDF files ready to write.
96	!
97	! In case of extend = .TRUE.:
98	! Find out if dimensions and variables of an existing file match the values
99	! of the actual run. If so, get all necessary informations (ids, etc.) from
100	! this file.
101	!
102	! Parameter av can assume values 0 (non-averaged data) and 1 (time averaged
103	! data)
