2022 Sea ice area and extent data
« on: January 02, 2022, 04:47:01 AM »
[ADS NIPR VISHOP (JAXA)] Arctic Sea Ice Extent.

In my ADS-NIPR-VISHOP posts, I have been using the same text for several months or years, so here I am looking to make an introduction and not repeat myself every day.

I post a table of values and a graph daily. The source of the data is:
https://ads.nipr.ac.jp/vishop/#/extent

On both attachments I usually include the 15 lowest values [by year on that day] and I will highlight 2010’s average (2010 to 2019), 2022 and the 5 years with daily lowest minimum, that are 2012, 2020, 2019, 2016 & 2007. I will include more years on the attachments, if 2022 or one of the 5 years with the lowest minimum are not within the 15 lowest. Sometimes I will also highlight 2000’s average and if there is not official value for some year, I will calculated it and post it highlighted in yellow.

On the ADS-NIPR-VISHOP values, we usually use the daily values and not the monthly averages. For a change, I will include here the September monthly averages, compared versus the 1979-2000 average.

I will look to make a deeper analysis and post it on the following topic:
https://forum.arctic-sea-ice.net/index.php/topic,3206.msg276104.html


Happy new year !!!  :)

Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

JAXA ARCTIC SEA ICE EXTENT:  12,696,772 KM2 as at 01-Jan-2022

- Extent gain on this day 55k, 16 k more than the average gain on this day (of the last 10 years) of 39k,
- Extent gain from minimum on this date is 8,084 k, which is 47 k, 0.6% less than the 10 year average of 8,131 k.

- Extent is 17th lowest in the 43 year satellite record

- Extent is  265 k MORE than 2020,
- Extent is  752 k MORE than  2018,
- Extent is  622 k MORE than 2017
- Extent is  50 k LESS than 2012
- Extent is  356 k MORE than the 2010's Average
_____________________________________________
On average 80.9% of extent gains  from minimum to maximum done, and 68 days to maximum

Projections. (Table JAXA-Arc1)

Average remaining extent gain (of the last 10 years) would produce a maximum in March 2021 of 14.61 million km2, 0.73 million km2 above the March 2017 record low maximum of 13.88 million km2, which would be 14th lowest in the satellite record

Hello Gerontocrat,
I don't know if that would make sense, but I wonder if calculating the trend on the actual year (2021-2022) and comparing it with the 10 years average trend would provide any interesting information.

You are welcome.

My conviction is that weather make 2021 a good year for the Arctic sea ice, but climate change will make bad years in the near future. So, we should not catalog any year as "a recovery", just "a rebound". The question is how bad the next years will be.

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

JAXA ARCTIC SEA ICE EXTENT:  12,983,233 KM2 as at 07-Jan-2022

- Extent gain on this day 41k, 8 k more than the average gain on this day (of the last 10 years) of 33k,
- Extent gain from minimum on this date is 8,370 k, which is 2 k, 0.0% less than the 10 year average of 8,372 k.

- Extent is 18th lowest in the 43 year satellite record

- Extent is  526 k MORE than 2021,
- Extent is  325 k MORE than 2020,
- Extent is  775 k MORE than  2018,
- Extent is  647 k MORE than 2017
- Extent is  86 k MORE than 2012
- Extent is  393 k MORE than the 2010's Average
_____________________________________________
On average 83.3% of extent gains  from minimum to maximum done, and 62 days to maximum

Projections. (Table JAXA-Arc1)

Average remaining extent gain (of the last 10 years) would produce a maximum in March 2021 of 14.66 million km2, 0.78 million km2 above the March 2017 record low maximum of 13.88 million km2, which would be 14th lowest in the satellite record

By now the 7 High Arctic seas are more or less completely frozen over. So here is a look at what is happening in the 7 peripheral seas

NSIDC - ARCTIC PERIPHERAL SEA ICE AREA (5-day trailing average):  3,294,888 KM2 as at 08-Jan-2022

- Area gain on this day 53k, 29 k more than the average gain on this day (of the last 10 years) of 24k,
- Area gain from minimum on this date is 3,259 k, which is 239 k, 7.9% more than the 10 year average of 3,020 k.

- Area is at position #13 in the satellite record

- Area is  103 k MORE than 2020,
- Area is  8 k MORE than  2019,
- Area is  306 k MORE than 2018
- Area is  331 k MORE than 2017
- Area is  128 k MORE than the 2010's Average
_____________________________________________
On average 69.2% of Area gain  from minimum to maximum done, and 64 days to maximum

Projections.

Average remaining Area gain (of the last 10 years) would produce a maximum in March 2021 of 4.64 million km2, 0.52 million km2 above the March 2017 record low maximum of 4.11 million km2, which would be 12th lowest in the satellite record.

[ADS NIPR VISHOP (JAXA)] Arctic Sea Ice Extent.

Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.
