ECMWF HRES Resolution and Accuracy over Europe

1 / 5

ECMWF HRES is the deterministic flagship model at ~9 km horizontal resolution with 137 vertical levels out to 10 days, and it remains the institutional baseline for European energy traders.

2 / 5

Accuracy over Europe degrades most sharply between 72 h and 120 h for wind, temperature, and solar radiation, with effective resolution dropping further over complex terrain such as the Alps.

3 / 5

Independent StationBench verification shows Jua’s EPT-2 outperforming HRES on 10 m wind, 100 m wind, 2 m temperature, and surface solar radiation at every lead time from 0–240 h.

4 / 5

Energy traders can keep HRES for its validation record while running Jua for Energy alongside it to replace manual pipelines, benchmarking, and dashboard stitching.
