Forecast verification — HRRR + RRFS vs URMA
Compares what HRRR and RRFS predicted vs what URMA observed over the past 24h. URMA is NOAA’s analysis-of-record — a higher-quality rerun of RTMA with late-arriving obs. MAE (Mean Absolute Error) quantifies forecast skill.

AIFS — ECMWF AI forecast system
ECMWF’s machine-learning weather model, trained on ERA5 reanalysis. Runs on ECMWF’s GPU cluster at 0.25° resolution (25km). Produces 15-day forecasts in seconds vs hours for IFS. Uses graph neural networks to learn atmospheric dynamics directly from data. Competitive with IFS on many metrics, especially in the tropics and for medium-range.
