38	! for extended NetCDF files, the updated title attribute includes an update of
39	! time_average_text where appropriate.
40	! Bugfix for extended NetCDF files: In order to avoid 'data mode' errors if
41	! updated attributes are larger than their original size, NF90_PUT_ATT is called
42	! in 'define mode' enclosed by NF90_REDEF and NF90_ENDDEF calls. This implies a
43	! possible performance loss; an alternative strategy would be to ensure equal
44	! attribute size in a job chain.
45	! NetCDF unit attribute in timeseries output in case of statistic
46	! regions added.
47	! Output of NetCDF messages with aid of message handling routine.
48	! Output of messages replaced by message handling routine.

76	! Description:
77	! ------------
78	! In case of extend = .FALSE.:
79	! Define all necessary dimensions, axes and variables for the different
80	! NetCDF datasets. This subroutine is called from check_open after a new
81	! dataset is created. It leaves the open NetCDF files ready to write.
82	!
83	! In case of extend = .TRUE.:
84	! Find out if dimensions and variables of an existing file match the values
85	! of the actual run. If so, get all necessary informations (ids, etc.) from
86	! this file.
87	!
88	! Parameter av can assume values 0 (non-averaged data) and 1 (time averaged
89	! data)
