As noted in a previous post, March marks the moment of truth regarding the Arctic maximum extent. Now ten days later 2020 met the challenge.

For ice extent in the Arctic, the bar is set at 15M km2. The average in the last 13 years occurs on day 62 at 15.04M before descending. Six of the last 13 years were able to clear 15M, but recently only 2014 and 2016 ice extents cleared the bar at 15M km2; the others came up short.

As of yesterday, 2020 cleared 15M km2 as recorded both by MASIE and SII.

During February MASIE and SII both show ice extent hovering around the 13 year average, matching it exactly on day 52 at 14.85M km2. Then the ice cover shrank before growing strongly the last five days to overtake the 13 year average on day 61 at 15.05M km2.
