SPG12

ANHA4-SPG12 is a regional ANHA4 configuration with a single AGRIF nest in the North Atlantic Subpolar gyre, bringing local resolution to 1/12 of a degree. This and all of our AGRIF simulations use two-way feedback: the ANHA4 parent domain provides the boundary conditions for the SPG12 nest each model timestep; The SPG12 nest supplies its’ solution back to the ANHA4 parent domain
