Description

  1. Difficult to find, does not show up in search (needs search term adding)

  2. https://docs.dart.ucar.edu/en/latest/assimilation_code/modules/assimilation/filter_mod.html#namelist

Is this true? (No?) That a list of files is not supported. The option is in the code

input_state_files character(len=256), dimension(MAXFILES) A list of the NetCDF files to open to read the state vectors. Models using multiple domains must put the domain and ensemble numbers in the file names. The order and format of those is to be determined. NOT SUPPORTED as of March, 2017.

"The order and format of those is to be determined." 🙃

Same table for output_state_files:

output_state_files character(len=256), dimension(MAXFILES) A list of the netCDF files to open for writing updated state vectors. Not supported when using multiple domains.

The first search result for filter_nml is "diffs from lanai" which has a subset of namelist options, talks about list of files for small models.

Research direction

Start with the linked filter_mod namelist documentation and the Manhattan_diffs_from_Lanai.html filter_nml page. Compare their input_state_files and output_state_files descriptions with the current filter_nml implementation, then update the search term and tables so supported file-list behavior and naming limitations are accurate.
