What is the Sea-Ice & SST Viewer?

The Sea-Ice Viewer visualises the sea-ice data covering the northern polar region.  Three presentations are available:  sea-ice concentration, sea-ice type (old or new), and sea-ice edges (open or closely packed).


What data does it read?

OSI-SAF data available from the EUMETCast system (as used for Meteosat-8 reception) or data FTPed from the Internet (  Because the sea-ice data is only sent once per day, between 04:00 and 04:30 UTC, unless you run your system 24 hours per day you may miss the data.  For this reason, you may need the FTP service from Norway.  If you want to automate the FTP downloads, please contact me for a suitable command-file.


What do the results look like?

Can I register and what do I get?

Whilst the free version of the program will provide basic viewing of the sea-ice concentration and sea-surface temperature data, you get the following extras with registration:

  • display of the sea-ice type data
  • display of the sea-ice edge data
  • display of country boundaries and gridlines
  • display of southern hemisphere data
  • fast access to the most recent data
  • the ability to animate the sea-ice data
  • the ability to save the results
  • the ability to run the program from the command-line
  • the ability to automate the program

Further developments will be concentrated on the registered version.

Please see the read-me file which comes with the program for more information about command-line operation and automating the registered version of the program.

NetCDF format

EUMETSAT have announced that they are to discontinue OSI SAF SST products in GRIB format from 12 January 2017.  A couple of alternatives have been suggested by Simon Proud, and reports of any experiences with these viewers would be welcome in the SatSignal self-help group.
