How does IJIS relate to the data published at NSDIC? Are they different data sets or a different way of presenting a moving average of the same data? If I understand what has been said as to how the 2-day delayed average is determined for IJIS, the final sea ice extent for Dec 31 will in fact be the average of Dec 29 and Dec 30.

Based on trends seen at NSDIC, and if there is only 1 more day reported for IJIS, it looks like the final SIE will be about 12,150,000 km2, meaning it will be about tied for the lowest extent ever.

Different data sets, different algorithms used.


Thanks. I was wrong on final extent, but the final number was still 12M+ so those who guessed 12-12.5 won!
