#2692 new Defect

Update of AGRIF reference configuration

Reported by: jchanut Owned by: jchanut
Priority: high Milestone:
Component: AGRIF Version: trunk
Severity: minor Keywords:



Update the reference configuration to demonstrate and test AGRIF capabilities, e.g. "AGRIF_DEMO"


AGRIF_DEMO is based on ORCA2 in which 3 nested grids are embedded:

  • The first zoom is a 1:1 refinement of ORCA2 to detect trivial errors in the implementation
  • The second zoom is 1:4 refinement spanning a part of the Arctic Ocean. The positioning of this grid close to the North Fold was ill posed and generates reproducibility issues.
  • The third zoom is nested in zoom 2, over the Svalbard archipelago.

Since new functionalities in the upcoming NEMO 4.2 need to be tested (vertical refinement, nested grids crossing the North Fold, etc...), and because constrains on grid matching have evolved since NEMO 4.0x, a new configuration needs to be created.

#2692, Update AGRIF_DEMO parameters (initial state interpolation from parent will be tested). Changed default agrif parameters in namelist_ref so that bathymetry checking is now the default.
