6.1 GCM Projections Across Arctic Basins
Regarding the first investigation topic, on the relevance of GCM projections, the results
highlight the improvements in basin-scale climate model simulation of temperature and
precipitation between the TAR and AR4 generation of GCMs. However, the analysis also
identifies some remaining limitations in precipitation simulations.
