🌎 We developed an ML-based atmospheric model suitable for climate prediction! Long-term stable, capable of assessing mass/moisture conservation, and predicts diagnostics for (eventually) coupling to ocean.

Very excited about this project! 🎉

[Ai2 Climate Modeling @ai2_climate]

We're excited to present ACE (AI2 Climate Emulator), a long-term (at least 10 yr) stable ML emulator of a comprehensive 100-km resolution global atmospheric model: https://t.co/1Rd3a9XDXd

🌍☀️❄️ Can AI forecast year-to-year differences in the seasons?
New research with @metofficeUK shows our ACE2 ML model demonstrates seasonal forecasting skill—matching traditional physics-based methods while using dramatically less compute. 🧵

[Ai2 @allen_ai]

We partnered with researchers @UCSanDiego and @ucsd_cse to supercharge climate modeling, speeding up predictions and enhancing accuracy.🌍 Check out the blog post below and come find us at #NeurIPS this week!

We are delighted to announce the #ICML2024 ML4ESM Best Paper Award winner:

[2406.14798] Probabilistic Emulation of a Global Climate Model with Spherical DYffusion (https://t.co/zEuA5qC3Vu)

Congrats to @salvaRC7 and co-authors @ai2_climate @yuqirose for their amazing work!

[ml4esmworkshop @ml4esmworkshop]

Hope everyone is enjoying #ICML2024! Don't forget to stop by our workshop on Machine Learning for Earth System Modeling tomorrow, Friday 26th in Stolz 1! Schedule here: https://t.co/PuxJJrNfvQ

[Oliver Watt-Meyer @oliwm]

Great work on probabilistic emulation of an atmospheric model from @salvaRC7 who interned on our @ai2_climate team!

[Salva Rühling Cachay @salvaRC7]

🌍We've developed the first conditional generative model for accurate & efficient ensemble climate simulations!

How can AI help us prepare for a changing climate? That's one of the big questions our climate modeling senior director Chris Bretherton wants to answer. Chris spoke with @nvidia's @noahkravitz about how technology like localized models can help us prepare for the future — listen here: https://t.co/cHbpJIGvlr

[Ai2 Climate Modeling @ai2_climate]

We have a new ACE preprint led by our former intern, James Duncan, where we’ve successfully emulated a second major atmospheric model, DOE’s EAMv2! 🌎💻

[Brian Henn @BrianMHenn1]

Was interesting to see how well a simple ML approach could learn skillful climate model cloud patterns that could improve coarse-grid model climate

[Oliver Watt-Meyer @oliwm]

Recently out in JAMES!

[Ai2 Climate Modeling @ai2_climate]

A new published article, led by @oliwm, investigates direct learning of heating/moistening rates from a coarsened 3 km (realistic topography!) storm-resolving simulation for use in a 200 km global climate model. 🌡🌧🌐

For those of you at @ametsoc's #AMS2024 this week, there will be two @ai2_climate in-person presentations on Tuesday. Andre Perkins (@frodre) is presenting on ML emulation of climate model microphysics https://t.co/RXSCtqD4kh

[Blanka Balogh (@blankabalogh.bsky.social) @BlankaBalogh_]

Did you like the IA NWP models? You'll love the AI climate models!
The authors present a climate model based on SFNO block, and with an impressive numerical stability of 10 years (!) at least.

It was a breakthrough year for environmental AI, with many new foundation models and innovative solutions for tackling our biggest environmental challenges. Learn more about 2023's major advances and key themes in climate and sustainability research: https://t.co/t1ICk9XYly

[Oliver Watt-Meyer @oliwm]

@janniyuval For stability, choice in architecture, input variables (insolation, surface height), and normalization strategy all led to improvements. Our dataset on gaussian grid is also well suited for the architecture we used. Haven't done enough ablations to say exactly which matters most.

[Oliver Watt-Meyer @oliwm]

@janniyuval We have some blurring but less than what I've seen for models using 0.25° ERA5. Using 1° data makes it easier. But also we only optimize over a single 6hr step which makes a big difference.

[Oliver Watt-Meyer @oliwm]

@shoyer Absolutely!

[Oliver Watt-Meyer @oliwm]

Updated version of AI2 Climate Emulator (ACE) paper with:
-> 100 year run ⌚️
-> testing on unseen realistic SST dataset 🌍
-> code+data+checkpoint released https://t.co/uiZ7LwleAb
https://t.co/sVeMR9FoSC

[Ai2 Climate Modeling @ai2_climate]

The updated ACE arxiv paper is available, now with code release https://t.co/1Rd3a9XDXd . We're excited to get to share these results with the community!
