Sea Ice Extent (Global Antarctic and Arctic) – Day 101- 2016

NSIDC has this message on their website.



An example:




  1. I noticed this problem when it first occurred April 7, and now it happens again today in report April 10 ice extents. Here are the NH stats for the last six days from SII (Sea Ice Index) in M km2:

    2016 4 5 14.001
    2016 4 6 14.016
    2016 4 7 15.065
    2016 4 8 14.318
    2016 4 9 14.274
    2016 4 10 15.032

    Spikes of 1M km2 at this time of year? I don’t think so. And of course, MASIE shows no such thing. However, SII did successfully align with MASIE on April 8.

  2. This has been happening a LOT in the past year or so, both on Arctic and Antarctic polar views. Is there a problem with the satellite or with the processing algorithm? Would be interesting to know.
