Semimonthly BOE evaluation
As of August 31st, extent is 3,943,313 km2. With on average 13 days to go until the end of the melt season on September 13th, we now require a daily drop of -226,409 km2 for a BOE to occur. (See Attachment 1).
Total extent loss so far this season is -10,504,328 km2. This has resulted in the current season average daily drop of -58,035 km2. Since the year 2007, this is the 4th fastest average daily loss from maximum to August 31st (2007-2020). (See Attachment 2).
--- If the season ended today, total extent loss from maximum to minimum would be 2nd highest since 2007, behind only 2012. ---
Total extent loss from maximum to August 31st is 2nd highest on record in the post-2007 era, behind only 2012. (See Attachment 3).
Looking only at the month of August, 2020 lost -1,813,071 km2, averaging -58,486 km2 per day. Losing 5,000 km2 more than the average of -1,808,351 km2 in the post-2007 era, some ~700km2 less than 2012 lost in August. (See Attachment 4).
Finally, the 2007-2019 average ice loss for September 1st to maximum is -239,348 km2, with 2010 losing the most at -475,120 km2 and 2015 losing the least at -109,577 km2. Giving us a range for the minimum of 3,468,193 and 3,833,736 km2 respectively.
