JAXA ARCTIC EXTENT :- 10,036,880 km2(June 18, 2019)
- Extent is 6th lowest in the satellite record.
- Extent loss on this day 68 k, 10 k MORE than the average loss on this day of 58 k.
- Extent loss from maximum 4,234 k, 126 k (3.1 %) greater than the average of 4,108 k loss from maximum by this day,
- On average 41.6% of the melting season done, with 87 days to average date of minimum (13 September).
The Perils of Projections.
Average remaining melt would give a minimum of 4.26 million km2, 5th lowest in the satellite record, and 1.08 million km2 above the 2012 low of 3.18 million km2.
Looking at the last 5 years average remaining melt gives a result of 4.38 million km2, 6th lowest, and 1.20 million km2 above 2012.
Other Stuff
GFS showing more logical temperature anomalies at +1.4 to +2.2 degrees celsius. The images suggest high +ve anomalies at various times along most of the coastal fringes of the entire coastal fringe of the Arctic Ocean, except for contrasting and sometimes strong -ve anomalies for most of the time on land and sea by and in the Beaufort/CAA and the Kara Seas.
A day of above average extent loss in contrast to the series of daily extent losses that have been below average for the last 2 weeks. Melt remains only marginally above average. Average remaining melt data still points towards minimum well above 2012 and 2nd to 5th lowest. 2/5ths of the average melt in the season is now completed.
