Time Title Authors DAY 1 9:00 Welcome and logistics, Goals, Introduction Leif Toudal Pedersen, Lars-Anders Breivik, Tom Carrieres, Frank Kauker 9:30 Validation of a regional coupled ocean/sea ice model in Nares Strait Till Rasmussen 10:00 Development of operational coupled sea ice and ocean model at DMI Stiig Wilkenskjeld 10:15 Canceled 10:45 Break 11:15 Parameter sensitivity to assimilation of different data in a sea-ice model using the Ensemble Kalman Filter Christof Koenig Beatty 11:45 Assimilation of sea ice observations in a coupled ocean sea ice state estimate of the Labrador Sea using the adjoint method Ian Fenty 12:15 Lunch 13:30 Discussion: Is there an optimal ice model for all purposes or classes of models that are more appropriate to ice services or climate modeling. How close are we to having a linearized version of a coupled ice-ocean model? Moderator: Tom Carrieres 14:30 Assimilation of observed and unobserved ocean and sea ice Lars Axell 15:00 Break 15:30 Variational assimilation of hydrographic and ice concentration observations into a coupled ocean sea ice model of the Arctic Thomas Kaminski 15:45 Quantitative Network Design Thomas Kaminski 16:00 Adjoint analysis of the summer 2007 low in Arctic sea-ice area Frank Kauker 16:30 Discussion: Strengths and weaknesses of DA techniques and how each can benefit from the other. Moderator: Mark Buehner 19:30 Workshop Dinner at the Copenhagen Planetarium DAY 2 9:00 An overview of some Environment Canada sea ice data assimilation projects Tom Carrieres 9:30 Sea ice thickness categories and their error covariances for assimilation with a three-dimensional variational data assimilation system Alain Caya 10:00 Towards the use of high-resolution remote sensing data in a three-dimensional variational analysis system: A collaboration with OSI-SAF Mark Buehner 10:30 Break 11:00 Assessment of the ECCO2 regional optimized solution in the Arctic An T. Nguyen 11:30 Discussion: Background error estimation, use of observations, etc. What are main sources of sea-ice background error (i.e. 12-24h forecasts):atmospheric forcing error? ocean forcing error? sciences of ice model? uncertain parameters (drag coeff., yield curve)? What fraction of the error can be explained by: ice displacement errors? melt/growth errors?Moderator: Lars-Anders Breivik 12:30 Lunch 13:30 The joint NSIDC and EUMETSAT sea ice re-analysis Rasmus Tonboe 14:00 The DAMOCLES project and beyond - recent advances in oceanographic observations in arctic regions and the legacy of IPY oceanography Jean Claude Gascard 14:30 Measurements of Arctic sea ice thickness with upward-looking sonars in 2004 and 2007 Joao Rodrigues 15:00 Break 15:30 OSI SAF SEA Ice products and their use in ocean-ice-model data assimilation Lars-Anders Breivik 16:00 The met.no ice chart archive Nick Hughes 16:30 Discussion: can models and data assimilations systems improve the utility of observations and re-analyses Moderator: Leif Toudal Pedersen DAY 3 9:00 Arctic Wide Ice Motion Estimation from Operational Satellite Imagery: improving the time span and accuracy of low resolution products Thomas Lavergne 9:30 High resolution Arctic Sea Ice drift Leif Toudal Pedersen 10:00 Satellite remote sensing of Arctic surface parameters at University of Bremen Christian Melsheimer 10:30 Break 11:00 Discussion: Intro by Thomas Lavergne - Satellite derived ice drift is NOT velocity. Operational sources of sea ice drift and thickness, error estimation and representativeness Moderator: Thomas Lavergne 12:00 Planning: collaboration, future meetings, etc. 12:30 Lunch, meeting end 13:30 IICWG IPY Project coordination
