International evaluation of Earth Sciences in Norway BCCR ranked at the top
nationally
The Evaluation Committee has an extremely positive overall impression of the centre
BCCR can be considered to be amongst the leading international organizations in the field of Climate Change research
High impact: papers cited 2x more often than national average

NorESM framework and model components
Development and drift of Earth system modelling
• 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
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
