Hugging Face AI Open Source Blog: HiRO-ACEv2: Simulating extreme weather at 3 km resolution for a fraction of the cost

Ai2 released HiRO-ACEv2; the new downscaling model HiROv2 can simultaneously predict multiple high-resolution elements, with high-resolution statistical errors within 3% for extreme wind, rain, and pressure events with a one-in-a-million probability. The system's cost to generate global 3km climate data is approximately 1/300 that of X-SHiELD, and hurricane energy in 10-year simulations is comparable to X-SHiELD, but it currently only works for climates aligned with X-SHiELD and does not yet support warmer futures or historical data such as ERA5.
