2022 Sea ice area and extent data

[Juan C. García]

[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:

Happy new year !!!

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.

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.
