Intercomparison

Intercomparison projects entailing participation of different international research groups have been conducted or are currently underway [29].

Intercomparison of these models [6] shows qualitative agreement between the projections, although specific projections of recovery rates can disagree significantly.

An evaluation of the different treatment of sea-ice rheologies (relationships between internal stresses and deformation) was the core task for the Sea-Ice Model Intercomparison Project (SIMIP) initiated in the late 1990s.

Currently, about a dozen Arctic Ocean models exist, most of which are participating in the Arctic Ocean Model Intercomparison Project (AOMIP) [60].

There are also a number of MIPs devoted to intercomparison of specific parameterizations employed in GCMs, including the Sea-Ice Model Intercomparison Project [45], the Snow Models Intercomparison Project [46], and polar clouds [47].

Other GCM MIPs of relevance to the ACIA include the Ocean Model Intercomparison Project [43], which is designed to stimulate the development of ocean models for climate research, and the Paleoclimate Modeling Intercomparison Project [44], which compares AGCM/OUML models (see Box 4.1) and AOGCMs in simulations of paleoclimate conditions during periods that were significantly different from the present-day climate.

A wider context of climate change simulations is provided by comparing the behavior of the five ACIA-designated AOGCMs in Phase 2 of the Coupled Model Intercomparison Project (CMIP2) [9] with the other 14 models included in that project.

However, the association found here between the initial sea-ice extent and the rate of ice retreat does not seem to be present in the Coupled Model Intercomparison Project suite of coupled global models [32].

Of the many international MIPs conducted in the past decade, two are of primary importance for the ACIA: the Atmospheric Model Intercomparison Project (AMIP) [34], and the Coupled Model Intercomparison Project (CMIP) [35].

Progress in mapping the spatial and seasonal distributions of arctic P has resulted from the use of information on gauge bias adjustment procedures, for example, from the World Meteorological Organization (WMO) Solid Precipitation Measurement Intercomparison [2].
