Happy to report the earliest (and final) stream for #ORAS6 has entered production. Just in the spinup period now, but we have some #reanalysis data valid in 1944 already. Now just to be patient until this reaches 1993 where the already produced stream awaits...

The promised plots.
I'll show data since 2003 only because only then did real measurements really kick off. Before that, measurements were so spotty with 1 in January in one year, then 3 years nothing, then 5 measurements in for example August and so on.
Data source for measurements is #NOAA https://www.ncei.noaa.gov/access/world-ocean-database-select/dbsearch.htmlThe other plot is from a #ReAnalysis called EN4.2 https://www.metoffice.gov.uk/hadobs/en4/download-en4-2-2.html#c14_analyses
It is based on the same NOAA data, and goes back to 1900. EN4.2 has better quality assurance than my download. And EN4.2 is able to calculate the likely values in adjacent coordinates and adjacent months.Among other Reanalyses, EN4.2 has also been used in the newest preprint by the Dutch team around #vanWesten. It sees AMOC tip in 2065 in RCP8.5 and in 2085 in RCP4.5. But it is based on biased Reanalyses and known-to-be too stable #CMIP6: https://arxiv.org/pdf/2407.19909
Whereas the first new preprint by van Westen's team, which tips AMOC 2037-2064, uses only real measurements of the 3 dedicated monitoring arrays in the North, tropical and South #Atlantic. https://arxiv.org/pdf/2406.11738
Here, the caveat is: very short data series.With measurements being so spotty, I only show monthly salinity 2003ff in down to 10m depth. And only from the area in the South Atlantic. Averaged on a 2 by 2 degree grid from Argentina's coast to longitude -48, and latitudes 40-48 South.
Sorry, not sorry: neither dataset shows a smoking gun. 😁

To #HindsgavlSlot to meet with #Danish #ArcticScience community for first time in 3 years. Always fun to find out what our colleagues in terrestrial #ecosystems, #greenhouseGases etc are working in
After the #COVID19 pandemic, I'm pleased to see the focus is on #ECRs and giving them a chance to network and present.
I'm especially keen to talk #CARRA + #CARRA2 (#Copernicus #Arctic Regional ##Reanalysis) to any users, potential users or data providers out there...

CW: Introduction #DA
My day job is to improve weather forecast by using information from models and observations of the #ocean and #seaice to give a better estimate of the current state of the Earth system
This means sitting at a desk coding, but also engaging with people who know a lot more than I do!
I'm currently working hard on the next gen ocean #reanalysis, to feed into #NWP and hopefully #ERA6 soon. My focus is on #seaice #DataAssimilation and coupled #SST #DA
I moonlight as a cake tester 🍰

Jason Box is now talking about #PROMICE data in #CARRA (#Copernicus #Arctic Regional #Reanalysis) and using the latest insights for understanding the #Greenland #IceSheet
The trend shows increasing #precipitation but not #snow - it's falling as #rain...
