ANHA [/ˈæn ɑ:/]

stands for Arctic and Northern Hemisphere Atlantic. It covers the whole Arctic Ocean, North Atlantic and a part of South Atlantic with two open boundaries, one close to Bering Strait and the other one align at 20oS. The mesh grid is extracted from the global ORCA tripolar grid.
ANHA is first set up for the VITALS project, focusing on the ocean, sea ice and biochemistry processes in northern high-latitude ocean, especially in Labrador Sea.
