11th International Workshop on Sea Ice Modelling, Assimilation, Observations, Predictions and Verification

21-22-23 March 2023 hosted by the Norwegian Meteorological Institute, in Oslo, Norway


A joint workshop of the International Ice Charting Working Group (IICWG), the Norwegian Meteorological Institute, the EUMETSAT Ocean and Satellite Application Facility (OSI SAF), the European Space Agency Climate Change Initiative for Sea Ice (ESA CCI), and the Sea Ice Retrieval and Data Assimilation in Norway (SIRANO).


The workshop, which is the 11th in a series organized with the International Ice Charting Working Group (IICWG), aims at improving international capabilities to perform sea ice prediction on timescales ranging from hours to a season. The aim of the workshop is to discuss cross-cutting issues in sea ice modelling, assimilation and observations and how deficiencies of current systems can be diagnosed and addressed more efficiently. 

General topics (sessions) include: 

  • Sea ice data assimilation (methods and results) 
  • Sea ice observations and uncertainties 
  • Sea ice model parameterizations and coupling to ocean and atmosphere models 
  • Verification approaches for sea ice analyses and forecasts
  • Recent research to sea ice operation transfer—Automated prediction systems


The workshop will be organized around keynote and contributed presentations with ample time for discussion. All attendees are encouraged to make a contribution, please specify your preference for oral or poster presentation. Online participation will be possible, depending on the covid-19 situation and expression of interest.

We appreciate your abstract submission to the workshop no later than 1 November 2022. Participants will be contacted by 15 December 2022 regarding their proposed contribution.
