localGP collection design

localGP grids come in a few similar flavors: integrals over pressure ranges; interpolations to specific pressure levels; and unleveled grids, like mixed layer depth or sea height. All of these can be represented as Argovis-schema grids, with the generalization that integral grids need ranges allowed in the 'levels' property of their metadata.

integral grids

• plan (Dec 2025) is to combine all the future integral grids onto a single collection localGPintegral, with metadata on localGPMeta.
  • advantage: minimal document number -> minimal index size
  • problems: assumes every variable that gets added has a similar level spectrum, otherwise we're going to end up with a lot of null padding.
• create collection schema with the usual grid scripts from db-schema repo.
• see populate_db.py for run instructions
  • built to consume localGP full field matlab outputs describing a single variable on [20.5,379.5] and [-89.5,89.5].

interp grids and unleveled grids

• TBD. probably just regular grids, questions remain ATOW what level spectra will be used, how consistent this will be.
