Development and drift of Earth system modelling Atmospheric chemistry CAM CLM CICE River routing MICOM HAMOCC NorESM framework and model components • 600+ model years of pre-industrial spinup completed. The integration is being analysed for model quality and drift • Production runs started early Feb 2011 • The production period will last 3-4 months • 2200+ model years will be produced • Total storage requirement is estimated to 150TB Components in blue communicate trough a coupling component. Components inred are subroutines of blue components.
External forcing and Atlantic variability Otterå et al. (2010), Nature Geoscience A recent study indicate that volcanic eruptions can have a proufound impact on climate not only short term climate variability, but also for variability on longer time scales
