AOMIP
The Arctic Ocean Model Intercomparison Project (AOMIP) is an international effort comparing different numerical models of the Arctic Ocean under realistic forcing. Goals are to examine the ability of Arctic Ocean models to simulate variability on seasonal to interannual scales, and to understand qualitatively and quantitatively the different behaviours of different Arctic Ocean models. In this way AOMIP participants seek to identify and to correct systematic errors.
Nine modeling groups participate in AOMIP:
| Code | Institution | Country |
| AWI | Alfred Wegener Institute | Germany |
| GSFC | Goddard Space Flight Center | USA |
| IOS | Institute of Ocean Sciences | Canada |
| LANL | Los Alamos National Laboratory | USA |
| NPS | Naval Postgraduate School | USA |
| NYU | New York University | USA |
| RAS | Russian Academy of Science | Russia |
| UAF | University of Alaska at Fairbanks | USA |
| UW | University of Washington | USA |
A list of detailed specifications for the models is available (in construction). Complete AOMIP project information can be found at the AOMIP home site.
Two tables compare how the different models represent the transport and distribution of Atlantic Water in the Arctic. The first table gives results at 500m depth. The second gives vertical sections near Fram Strait.

Trying to understand the reasons for differences among the models is a huge, ongoing task by many investigators. One part of that overall effort is described on an accompanying page.
