Ocean Circulation and Climate Dynamics


Indian Ocean and Atlantic Nest at 1/10°

Global Bathymetry (based on BlueMarble by the NASA Visible Earth Project). Boundaries of the AGRIF nest are shown as yellow frame.

INALT01 is the successor of AG01, now resolving the South Atlantic at 1/10° resolution.


Successor will be INALT20 (summer 2015).

Person in charge: Jonathan Durgadoo


  • NEMO ocean
  • LIM2 sea ice (elastic-viscous rheology)
  • Tripolar ORCA grid
  • Total Grid Points: 45 Mill
  • Grid Points: 1404 x 659 x 46
  • Typical Grid Point Distance: ~9 km
