Arakawa grid
WebFacebook WebThe native interlaced horizonal velocity and conserved tracer (e.g. temperature and salinity) grids form a tripolar Arakawa-B grid, varying from 0.1°x0.25° at high latitude to 1/4°x1/4° in the tropics (quasi-isotropic grid spacing increases from ~11.7km at 65 latitude to ~28.0km at the Equator, 1440x1070 grid points).
