European Weather Service: New AI weather model needs 1000 times less electricity.

The European Center for Medium-Range Weather Forecasts (ECMWF) is making available data from a new AI-based weather model that is significantly more accurate and requires around 1000 times less energy to produce a forecast.

(Please also see Phil Browne's comment below for ECMWF's open data plans)

There are a quite a lot of weather companies and even national weather services around the world that depend on the freely and reliably available global model data from the US NWS.

There is now a real risk that this access will be shut off or made unaffordable.

I really do hope that @ECMWF is thinking about this and considering to finally make their model data freely available for at least non-member state weather services - in particular in the global south.

IMO the model data in full should be free for everyone (like the US data has been for decades) since it is tax payer funded and would allow weather companies around the world to run their own models and innovate products and services.

I've always found it ironic that the US is so much more generous with their data than the "socialist" Europeans are.

"9 of the first 10 months this year, and 15 of the last 16 months exceeded 1.5°C global average surface air temperature compared to pre-industrial levels."

Look. These high September temperatures in Greifswald and Potsdam had already been physically possible 110 to 130 years ago, when #GlobalWarming was at ±0°C.
It merely only happened once.

And today.

But we haven't experienced yet what the physically possible is in today's CO2-charged weather.
Knowing this would be very valuable regarding #climate adaptation.

Do you know where we can get such information on today's physically possible?

By exporting the maxima from each Forecast Ensemble Member since 2020.
A clickable map in a 1°by1° land-only grid, showing the maxima for °C, rain and stuff like 6-hour sustained °C and relative humidity, or 48hr rain and so on.

I asked the boss of #ECMWF Forecast but they don't want to produce such a clickable map. What they did give me:
a URL to past Ensemble Member data so I can do it myself ! #OpenData https://confluence.ecmwf.int/display/TIGGE/TIGGE+archive

Had a quick look at #Tigge but it's too hot for my poor brain to make sense of it. Maybe this winter. Or you?

#ECMWF needs your input to enhance their open-data offerings. Earlier this year, they released the IFS and AI-based AIFS models at a 0.25° resolution. Now, they want to hear from you on how their data is being used to help shape the direction of their future offerings.

Mammuts und Saurier haben sich vermutlich nicht selbst ausgerottet. Die Menschheit kriegt das hin.

#ECMWF did some *great* work in this one.

After a week of training on 64 a100 40GB GPUs (in a 4GPU per host configuration), you can produce a model that’s competitive with SOTA using a single A100 for 3 minutes

World's first year-long breach of key 1.5C warming limit - #BBCNews
https://www.bbc.com/news/science-environment-68110310

'World leaders promised in 2015 to try to limit the long-term temperature rise to 1.5C, which is seen as crucial to help avoid the most damaging impacts.
This first year-long breach doesn't break that landmark 'Paris agreement', but it does bring the world closer to doing so in the long-term.'

Wanneer dringt het door dat nieuwe records geen teken van succes zijn?
