The workshop will take place on February 18-19 2013 at the Danish Meteorological Institute in Copenhagen and is sponsored by the European Space Agency (ESA), WCRP Climate and Cryosphere (CliC) Project Office and the Danish Meteorological Institute.

Sea ice concentration from satellite microwave radiometry is our primary source of information on the annual sea ice extent minimum as well as a large variety of other properties of the large scale sea ice cover of the Earth. For this workshop we invite scientists developing and/or applying algorithms to derive sea ice concentration to participate in discussions of mutual interest.
The theme of the workshop will be passive microwave sea ice concentration algorithm inter-comparison and validation and we will deal with topics such as algorithm intercomparison, ice concentration validation in different regions and seasons, establishment of a common open validation database, new algorithm developments including fusion of microwave radiometer data with other data sources.

The organizers encourage participants to register their participation by email to Leif Toudal Pedersen (ltp@dmi.dk) as soon as possible and no later than January 20, 2013. Please provide a tentative title of a presentation of your work related to the above topics.

The workshop will promote the exchange of knowledge, ideas, and experience among many institutions and individuals who are involved in deriving climatological or near real time sea ice concentrations from passive microwave data.
