Arctic Multiyear ice concentration

The MYI data on this site are from a new satellite-based retrieval of sea ice type in the Arctic which can in principle distinguish YI, FYI and MYI. The retrieval method uses data from active and passive microwave instruments (radar scatterometer and radiometer, respectively), but then in addition applies several correction schemes to account for the effect of melt-refreeze processes, snow metamorphosis and sea ice drift on the sea ice type retrieval. Both air temperature and sea ice drift data are used in the corrections. As the retrieval does not work during the melt season, the data record usually spans October to May. Even during the winter season, the reitrieval can be problematic - see details
