DESCRIPTION:Every Finnish harbor gets ice blocked even during a mild winte
 r. Thus understanding sea ice is extremely important and there is a call f
 or high quality sea ice research. The sea ice research group at Finnish Me
 teorological Institute (FMI) conducts research on remote sensing and forec
 ast models for sea ice\, and develops charting methods and ice forecasts. 
 Our core objective is to produce reliable and user relevant information on
  sea ice. The end users range from those involved in winter navigation and
  offshore activities to policymakers and the general public in ice-covered
  sea regions.\n\nFor ice charting\, we use earth observation data obtained
  from current EO satellites as well as develop new methods for future sate
 llites. I will present some of our currently operational products\, such a
 s Baltic Sea ice charts and forecasts. I will also introduce novel sea ice
  thickness retrieval methods combining data from satellite synthetic apert
 ure radar\, passive microwave and optical sensors and ice models. I will a
 lso give a short overview of model development concerning sea ice dynamics
  – particularly from the viewpoint of ice compression felt by a ship nav
 igating through ice.\n\nFMI is also involved in reanalysis of long satelli
 te data series. As part of the European Space Agency's Climate Change Init
 iative we will reprocess the radar altimeter measurements from ERS-1\, ERS
 -2 and EnviSAT satellites. We will build an “Essential Climate Variable
 ” product of sea ice thickness covering the Arctic and spanning the wint
 ers 1993 – 2012. I will present the algorithms used in altimeter sea ice
  thickness retrieval\, introduce our prototype sea ice thickness processor
  and finally seek answers to some open questions concerning the sea ice th
 ickness retrieval.
