New Model_component : icon-land-1-1

[olafmorgenstern]

Component Type

land-surface

Component Name

ICON-Land-1-1

Component Family

None

Description

1. ICON-Land-1-1 simulates land physics, hydrology, the carbon and nutrient cycles, and land vegetation.
2. In concentration-driven simulations, ICON-Land-1-1 uses the JSBACH4 land surface model. In emission-driven simulations, ICON-Land-1-1 using the QUINCY formulation of land dynamics. The two differ in the treatment of the carbon and nutrient cycles and vegetation.
3. In both configurations, river discharge uses the HD hydrological discharge model at a 0.5 degrees resolution (h134). This is of completely different heritage, code, and grid structure to the rest of ICON-Land-1-1 (and is not listed separately, because only one "land-surface" model component can be registered).

Warning

Component (only) created.

Insufficient computational grids supplied. See below.

A horizontal and vertical computational grid are both required to generate a component_config record. Because one or both were not supplied, only the model_component record has been created in this PR.

Once your component is merged, use Stage 3: Link Existing Component to create the configuration by selecting:

• Model Component: icon-land-1-1
• Horizontal Grid: your h### from Stage 2a
• Vertical Grid: your v### from Stage 2b

The config ID will be auto-generated and pushed directly to src-data without a separate review.
