125	! Description:
126	! ------------
127	! In case of extend = .FALSE.:
128	! Define all necessary dimensions, axes and variables for the different
129	! netCDF datasets. This subroutine is called from check_open after a new
130	! dataset is created. It leaves the open netCDF files ready to write.
131	!
132	! In case of extend = .TRUE.:
133	! Find out if dimensions and variables of an existing file match the values
134	! of the actual run. If so, get all necessary informations (ids, etc.) from
135	! this file.
136	!
137	! Parameter av can assume values 0 (non-averaged data) and 1 (time averaged
138	! data)
