Detailed structure of an obs_seq file
Since the configuration of model ensembles and the characteristics of assimilated observations are highly variable, observation sequence files are highly adjustable to accomodate these variations.
There are many extensible parts of an observation sequence file. The following aspects of an observation sequence file can be adjusted:
the number of observation kinds contained in the file
whether the locations have one or more components
how many quality control values are available for each observation
where those quality control values come from
how many copies of each observation there are
The following two diagrams demonstrate the structure of an
obs_seq.final file, respectively.
These example files are from entirely separate experiments. They were selected to demonstrate the flexibility of the observation sequence file format.
