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...

Hello from Reading! Our colleague Janna is currently at the NWP SAF Workshop on Satellite Observations of the Earth System Interfaces (https://events.ecmwf.int/event/420/). Exciting insights and discussions about how we can exploit #satellite #observations for numerical weather #predictions and #reanalysis even better!

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. 😁

Soil fractionation offers one way to try to tease out soil carbon dynamics beyond bulk. Using a linear-mixed effects model and large soil carbon database ( #ISRaD ) Heckman et al 2022 https://doi.org/10.1111/gcb.16023 found that depth was critical in explaining soil carbon stocks and persistence. Many traditional ClORPT variables were also explanatory, except for NPP, though their effects of different fractions differed. #SoilCarbon #DataCollection #Reanalysis #sciLit

Unprecedented!
The anomaly for September 2023 is:
the largest warm anomaly
of any month
of any year
in the ERA dataset (back to 1940)
September 2023 was around 1.75ºC above the preindustrial average

As we have more heat waves we also suffer from more heat stress.
Heat stress is more than temperature and is a metric that describes how the environment impacts people (temperature, humidity, wind, soil etc.)
Last summer Europeans saw more heat stress than ever before.

Data from the @copernicusecmwf the first 3 weeks of July have already broken several significant records, including:
Hottest day globally;
Hottest 3 weeks globally.C3S data also show:
July 2023 likely to be hottest month on record.More here: https://climate.copernicus.eu/july-2023-sees-multiple-global-temperature-records-broken

🌡️📈 Europe has been experiencing some of the hottest temperatures of summer 2023 so far.
But what is influencing this #heatwave, what are its potential consequences, & is #ClimateChange affecting it?

Global mean temperature exceeded 1.5 degrees threshold during the first days of June according to @CopernicusECMWF data.
Monitoring how often and for how long these breaches occur is more important than ever, if we are to avoid more severe consequences of the climate crisis.

In September 2022, Greenland saw record-breaking temperatures for the month and rain rather than snow, resulting in record ice sheet melt.
