Ai2 releases HiRO-ACEv2 to simulate extreme weather at 3 km resolution

Ai2 introduces HiRO-ACEv2, an update to its HiRO-ACE climate emulator that generates global 3 km climate data at about 1/300th the cost of X-SHiELD. The HiROv2 downscaling model predicts several high-resolution fields at once and reproduces rare rain, wind, and pressure extremes, matching X-SHiELD's statistics within 3%.

The system cannot yet produce data for other climates such as a warmer future, which Ai2 plans to address by training on new X-SHiELD datasets.
