HiRO-ACEv2: Simulating extreme weather at 3 km resolution for a fraction of the cost.

Ai2 BlogResearch source·
AI brief

HiRO-ACEv2 simulates extreme rain, wind, and pressure events at 3 km resolution at roughly 1/300th the cost of X-SHiELD.

Why it matters: The lower cost makes detailed global climate simulations more accessible to researchers.
