What new functionality do you need?

Enable GW to update the land model (NOAHMP) with ensemble and deterministic soil moisture and temperature increments in IAU mode . Current updates are done with a 6 hourly frequency. We want to do sub-hourly updates for land variables that have high temporal variability.

What are the requirements for the new functionality?

Read in GSI (and JEDI) increments
Re-grid increments to target/ native model grid
Apply updates as part of the land physics call

Acceptance Criteria

The updated soil fields match external test files

Suggest a solution (optional)

This brings land IAU work already in UFS WM to global workflow.
