Long Term Goals

• NIC: – global automated product as guidance to analyst and as

initialization for PIPS• DMI:

– extend spatial range and improve accuracy of regional model– automatic ice edge detection from SAR using data fusion

• Norway:– to develop a high resolution (1 km) analysis and forecast system

for the Svalbard area• Canada:

– to provide primarily automated analyses and forecasts over all operational areas, with requirement for minimal intervention from forecasters in high priority areas

Individual Goals to Report for Next Meeting

• Canada– extend statistical interpolation to include ssmi– evaluate relative weighting of model and daily ice

charts– assimilate image analysis charts

• Denmark– improve SAR ice edge detection

Individual Goals to Report for Next Meeting

• Norway– high resolution (1-5 km) model around Svalbard– nested system for driving high res model with

output from low res model

• United States– evaluate simple variational data assimilation

model– transition PIPS 3.0 and start collecting a dataset

for evaluation

Individual Goals to Report for Next Meeting

• Russia– adopt a model for Tatar Strait– estimate ice parameters that aren’t observed but

impact offshore structures– diagnostic model of ice dynamics including

inhomogeneous fields of thickness, etc.– assimilation of ice charts

Actions• Distribute information on the NASA Data Assimilation Workshop for

sea ice at Wood’s Hole to other members of science committee. Responsible: Mike Van Woert

• Report on NASA Data Assimilation Workshop. Responsible: Mike Van Woert

• IICWG recommends converting sea ice model output in a common data format netCDF in order to share/exchange data. Responsible: members of science committee

• Investigate the possibility of direct assimilation of passive microwave radiances, scatterometer backscatter, infrared radiances, visible reflectance. Responsible: members of science committee

Actions• In order to develop a structure to collaboration, identify national science

leads:• United States: Mike Van Woert• Norway: Lars-Anders Breivik• Canada: Tom Carrieres• Denmark: Rashpal Gill• Russia: Sergey Klyachkin

– Responsible: other IICWG national reps

• Focus of next science workshop will continue to emphasize modelling/data assimilation:

• advanced tutorials on models, satellite algorithms and data assimilation • model performance information incorporating guidance from CJRS paper

– Responsible: science committee

• Recommend that national model leads should attend and present latest results: IICWG members

Actions

• White Paper:– finalize and publish the White Paper on Data Assimilation under an

official publication. Responsible: Tom Carrieres, Lars-Anders Breivik

– provide national input to data, models and data assimilation inventory, national input to modelling system requirements, and further comment. Responsible: IICWG members and more specifically input from Baltic Sea Ice Services
