ACCESS-OM2 v1.0: a global ocean-sea ice model at three resolutions
We introduce ACCESS-OM2, a new version of the oceansea ice model of the Australian Community Climate and Earth System Simulator.ACCESS-OM2 is driven by a prescribed atmosphere (JRA55-do) but has been designed to form the oceansea ice component of the fully coupled (atmospherelandoceansea ice) ACCESS...
