122	! Description:
123	! ------------
124	! In case of extend = .FALSE.:
125	! Define all necessary dimensions, axes and variables for the different
126	! netCDF datasets. This subroutine is called from check_open after a new
127	! dataset is created. It leaves the open netCDF files ready to write.
128	!
129	! In case of extend = .TRUE.:
130	! Find out if dimensions and variables of an existing file match the values
131	! of the actual run. If so, get all necessary informations (ids, etc.) from
132	! this file.
133	!
134	! Parameter av can assume values 0 (non-averaged data) and 1 (time averaged
135	! data)
