🌎 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! 🎉

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: arxiv.org/abs/2310.02074

🌍☀️❄️ 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. 🧵

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: blogs.nvidia.com/ai-podcast/

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! 🌎💻 doi.org/10.22541/au.17…

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. arxiv.org/abs/2310.02074

@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.

@oliwm Thanks for sharing! Could you highlight what improved long term stability? Also, studies that used MSE loss had blurring. Do you have blurring?. A thought I had - blurring might not be a problem because of the ground truth that is more blurry than ERA5?

@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.
