JAXA ARTIC + ANTARCTIC SEA ICE EXTENT

It is April Fools' Day, so here is a look back at March

March '24 Global monthly average sea ice extent was 17.52 million km2, 8th lowest in the satellite record, 0.19 million km2 below the longterm linear trend, and 0.68 million km2 more than the March '23 average.

During March the Global sea ice extent 365 day trailing average continued to increase, up by 58k km2 in the month, 0.96 million km2 below the longterm linear trend, and 0.25 million km2 more than the record low in December '23. If sea ice change for the remainder of the year is at the 10 year average, the average will increase by about 0.80 million km2 by the end of Dec '24.

From then average daily losses continue until the false minimum in early/mid September.
Sea ice Area then normally makes the final run to the maximum in late October /early November.

The projected 2024 maximum is 19.78 million km2, 2.16 more than the November 2016 record low maximum of 17.61 million km2, which would be 5th  lowest in the 46 year satellite record

JAXA GLOBAL SEA ICE EXTENT:  18,948,481 KM2 as at 06-Apr-2024

- Extent gain on this day 20k, which is 35 k less than the average gain on this day (of the last 10 years) of 55k,
- Extent gain from minimum on this date is 2.92 million km2, 0.20 million km2, 7.5% more than the 10 year average gain of 2.72 million km2.

- Extent is 9th lowest in the 45 year satellite record

- Extent is  1.67 million km2 LESS than 1980's Average
- Extent is  0.52 million km2 LESS than 2010's Average
- Extent is  0.60 million km2 LESS than 2016
- Extent is  1.23 million km2 MORE than 2017
- Extent is  0.39 million km2 MORE than 2018
- Extent is  1.22 million km2 MORE than 2019
- Extent is  0.61 million km2 LESS than 2021
- Extent is  0.38 million km2 MORE than 2022
- Extent is  0.69 million km2 MORE than 2023

On average 31.0% of sea ice gain from minimum to maximum done, and 210.4 days to maximum

Projections of the Unknown Quantity. (Table JAXA-AA1)

Average remaining sea ice gain (of the last 10 years) would produce a maximum in November 2024 of 25.00 million km2, 1.24 million km2 above the record low of 23.76 million KM2 in 2016, and 6th lowest in the 46 year satellite record

In an average year sea ice reaches the false maximum in late June/ early July and the false minimum in early September, and then sea ice extent makes the final run to the maximum in late October /early November
