  1. 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...

  6. Paper alert🌧 Working in a region without high-resolution #precipitation data, and #reanalysis products show low performance? We used a rainfall generator and estimated the parameters from #ERA5-Land & #COSMO-REA6 data! #ProudSupervisor #hydrology #water

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

  9. 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 ncei.noaa.gov/access/world-oce

    The other plot is from a #ReAnalysis called EN4.2 metoffice.gov.uk/hadobs/en4/do
    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: 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. 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. 😁

  14. 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 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

  15. 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

  16. 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.

  17. 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.

  18. The #C3S monthly Climate Bulletin is out now:

    📈June was the warmest June globally at just over 0.5°C above average;
    📈 the North Atlantic saw record-high sea surface temperatures;
    📈#Antarctic sea ice reached its lowest extent for June on record at 17% below average.

  19. 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.

  20. 2nd warmest May - following
    4th warmest April and
    2nd warmest March
    Globally since 1950.

    The #C3S monthly Climate Bulletin is out now:

    📈 #Antarctic sea ice extent reached a record low monthly value at 17% below average;
    📈 Conditions were drier-than-average in the Iberian Peninsula.

  21. The #CopernicusClimate monthly Climate Bulletin is out:

    📈Last month was joint 4th warmest April globally
    📈#Antarctic sea ice extent was 3rd lowest on record for April
    📈April was wetter than average in a large west-to-east band from Ireland & across Central Europe

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

  28. 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...

  33. 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 🍰
