I have a question. If you go to this web site, ftp://sidads.colorado.edu/DATASETS/NOAA/G02186/latest/4km/masie_all_r00_4km.png you will see that they are claiming 10.9 million sq km of arctic ice. Look at the bottom left corner. What gives? Reply
This web site claims that there is 10.9 million sq. km of arctic sea ice. Is this right? ftp://sidads.colorado.edu/DATASETS/NOAA/G02186/latest/4km/masie_all_r00_4km.png Reply
Depends on the time of year etc. Some methodologies claim to be more accurate during melt season. Reply

And you use IJIS data?
NOAA
That’s about a 6% difference. Which method is correct, or more likely to be correct?
