• This product shall be referred to as: Sea ice edge product of the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF, www.osi-saf.org).

• Note, that during Arctic summer season (May-September) the ice type product is dubious because melting of the ice surface obscures the ice type signals. Similarly for SH, at present no ice type classification has been defined and SH product files do not contain valid classification.
• This product shall be referred to as: Sea ice type product of the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF, www.osi-saf.org).

• The emissivity is combined with the surface effective temperature, sometimes called the skin temperature, in the radiative transfer equation. Model simulations indicate that the snow-ice interface temperature or alternatively the 6 GHz brightness temperature is a closer proxy for the 50 GHz effective temperature than the snow surface or air temperature
• This product shall be referred to as the near 50GHz sea ice emissivity product of the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF, www.osi-saf.org).

• Note that the sea ice drift vectors during summer (May-September in NH, November-May in SH) are processed from the 18.7 GHz imagery of JAXA's GCOM-W1 AMSR2 instrument. The summer motion fields are of lower accuracy and coverage than those processed during the winter season, and this is reflected in the new uncertainty fields. Pay attention to the increased number of interpolated vectors (in variable status_flag).

• Due to pronounced cloud cover during summer, and occasional during winter periods, the daily data coverage can be very sparse.
• The mr ice drift production is based on TIR data during winter and VIS data during summer, with an overlapping period in spring and autumn.
