#amsr2 — Public Fediverse posts

Like the majority of our #SeaIce products, the Sea Ice Index is currently based on data from #JAXA 's #AMSR2 sensor. This sensor is being operationally replaced by its successor, #AMSR3, and we are currently adapting our products accordingly.

For more details: https://osi-saf.eumetsat.int/community/stories/implications-amsr2-being-replaced-amsr3-osi-saf-products.

Work-related: if you are curious about @osi_saf plans to transition their #seaice products from #AMSR2 to #AMSR3 over the summer, please visit https://osi-saf.eumetsat.int

And yes, worth noting that #OSISAF is on Mastodon. Thank you @gwenbras !

#SSMIS data-end grows close.

Our #SeaIce team has been busy this summer to ensure product continuity.

Our Sea Ice Index will be updated from v2.2 (SSMIS based) to v2.3 ( #AMSR2 based) from Friday 01/08/2025 on, but access to it will remain unchanged, ensuring a straightforward transition.

It now looks highly likely that the 2024 #Arctic #SeaIce minimum extent will prove to be 4.07 million km² on September 13th, using
#JAXA #AMSR2 data:

That is 4th lowest for the date, but the equal 5th lowest daily minimum in the satellite era:

Marina Durán Moro (MET Norway) carries assimilation of Level2 #SeaIce Concentration from #AMSR2 : from each orbit individually.

This performs better than assimilating daily average products, but there are regional dependency.

Jozef Rusin (PhD candidate at MET Norway and UiT) presents his research on Resolution Enhanced #SeaIceConcentration from #AMSR2 at #IICWGDA11.

The Alfred Wegener Institute's #AMSR2 based flavour of #Antarctic #SeaIce extent has also posted a new satellite era minimum.

#Arctic #SeaIce extent has been growing fast over the last 3 days, mostly in the Hudson Bay and Chukchi Sea.

Here is an animation of #SeaIce concentration coverage from the Japanese #satellite #AMSR2, processed by yours truly et al 😜.

Have a nice week-end when the time comes!

#Iceberg #A76 calved from the Ronne Ice Shelf in May 2021. It is about 170 km long and 25 km wide and weighs about 1000 Gt.
