Summer Modeling School
The Summer Modeling School will be an intensive Summer School that will bring current and future ice-sheet scientists together to develop better models for the projection of future sea-level rise (slr). The IPCC Fourth Assessment Report acknowledged that current models do not adequately treat the dynamic response of ice sheets to climate change, and that this is the largest uncertainty in assessing potential rapid slr. Recognizing this, an ice-sheet modelling Workshop was held during the July 2008 SCAR/IASC meeting, in St. Petersburg, Russia. This meeting developed a community strategy on how best to (i) improve the physical understanding of ice-sheet processes responsible for rapid change; (ii) incorporate improved physical understanding into numerical models; (iii) assimilate appropriate data into the models for calibration and validation; and (iv) develop prognostic whole ice-sheet models that better incorporate non-linear ice-sheet response to environmental forcing (such as change in surface mass balance, loss of buttressing from floating ice shelves and ice tongues, and rising sea level).
The two-week Summer School is a first step towards implementing this strategy. It will bring scientists from differing backgrounds together and allow more extensive and in-depth interactions between the relevant polar research communities. A series of general background lectures as well as discussions of more specialized and advanced topics during this Summer School will provide the foundation for cross-disciplinary research, particularly for early career scientists. We anticipate publication of lecture notes both in hard copy and on a dedicated home page, to provide the glaciological community with an up-to-date overview of the science and observational techniques that will serve to guide further research efforts. Direct beneficiaries will be young researchers; indirect beneficiaries will be coastal zone communities who will gain improved sea level change forecasts to underpin their plans for sustainable development.
The modeling school will be held in Portland, Oregon August 3-14, 2009.
