General Use Cases

[atteggiani]

This is a list of use cases for the um-modify function that will guide its development.
Please feel free to add to the list below.

Use Cases

• Modification of a restart/initial condition file
• Modification of ancillary files for forcing Boundary Conditions
• Handle files with tiles (land files)
• Files with timeseries (properly handle them or make it clear they are not supported with an error)

Just as a very specific example use case:

When I was at Monash, I worked on an ESM1.5 AMIP run where we used modified SST and sea ice ancillaries. We did all the processing in netCDF, and then used Xancil to convert it over to the correct ancillary format. This step was a bit clunky, and I had to make sure I'd correctly set all the various Xancil settings to produce the right type of file for ESM1.5. Being able to just swap the data in a correctly formatted file would be great for this!

Another example I can think of: Here is a script used by paleo researchers when setting up ESM1.5 ancillaries. It regrids data and places it into a specified ancillary file. Potentially this sort of script could make use of um-modify.

Thank you @blimlim. Those are great use cases!

I think they would be both covered in the Modification of ancillary files for forcing Boundary Conditions, what do you think?

I agree!
