ANHA2

ANHA2 horizontal mesh

ANHA2 horizontal mesh (every 5 grids, color shows the resolution in kilometers)

ANHA2 is a sub-domain of the global ORCA05 mesh.



ANHA4

ANHA4 horizontal mesh

ANHA4 horizontal mesh (every 10 grids, color shows the resolution in kilometers)

ANHA4 is a sub-domain of the global ORCA025 mesh.



ANHA12

ANHA12 horizontal mesh

ANHA12 horizontal mesh (every 20 grids, color shows the resolution in kilometers)

ANHA12 is a sub-domain of the global ORCA12 mesh. The highest horizontal resolution (~1.93km) is in Dease Strait (near the artificial pole over northern Canada), and the lowest resolution (~9.3km) at the equator. In vertical, 50 levels with layer thickness smoothly increased from 1.05m at the surface to 453.13m at the last level. Enhanced resolution is applied to the surface layer (<2m resolution for top 10m). Partial steps is also utilized to better resolve the sea floor.



ANHA4-SPG12

ANHA4-SPG12 horizontal mesh

ANHA4-SPG12 (color shows the resolution in kilometers)

ANHA4-SPG12 is ANHA4 with 1/12 degree nesting in the North Atlantic Subpolar region.



ANHA4-CAA12

ANHA4-CAA12 horizontal mesh

ANHA4-CAA12 (color shows the resolution in kilometers)

ANHA4-CAA12 is ANHA4 with 1/12 degree nesting in the Canadian Arctic Archipelago region.



ANHA4-GRE12

ANHA4-GRE12 horizontal mesh

ANHA4-GRE12 (color shows the resolution in kilometers)

ANHA4-GRE12 is (75-levels) ANHA4 with 1/12 degree nesting in Baffin Bay, Greenland coast and Nordic Sea region.



ANHA4-SPG12-LAB60

ANHA4-SPG12-LAB60 horizontal mesh

ANHA4-SPG12-LAB60 (color shows the resolution in kilometers)

A nearly identical configuration as ANHA4-SPG12, but with an additional inner nest with 1/60th of a degree in the Labrador Sea and 75 vertical levels.



NAA

NAA horizontal mesh

NAA horizontal mesh (every 10 grids, color shows the resolution in kilometers)

NAA (North Atlantic and Arctic) is a pan-Arctic configuration (quasi 1/4 degree horiztonal resolution) used in the group before the birth of ANHA. This configuration has been successfully applied to study several freshwater processes in the arctic regions, e.g., the pathways of Pacific Water in the Arctic Ocean; the impact of Greenland meltwater on Baffin Bay heat content, sea surface height, circulation as well as the CAA throughflow; sea ice conditions and ocean circulation changes in the future climate projection.
