UPDATE: All the graphs are here.
Jaxa is one of the other sea ice monitoring agencies. They just came out with a version 2 of their data.
I thought … why not graph the difference between version 1 and version 2 for 2013.
Red = Version 2 Lower Than Version 1
Blue = Version 2 Higher Than Version 1
Guess what the following graph shows? It makes the minimum dramatically lower (400,000 sq km lower) and the maximum higher so the minimum looks even worse when graphed.
