GribStream

GraphCast Global Forecast System (GFS GraphCast)

GribStream-Code: graphcast

Status: GribStream bietet graphcast als historisches experimentelles Archiv an. Die GraphCastGFS-Abdeckung in GribStream reicht bis zum Lauf 2026-05-05 00:00 UTC. Das NOAA EAGLE Registry beschreibt AIGFS und AIGEFS als operative Nachfolger der EAGLE SOLO/Ensemble-Linie. Nutzen Sie daher AIGFS oder AIGEFS für aktuelle globale KI-basierte NOAA-Vorhersagen.

Beschreibung

GraphCast Global Forecast System ist eine experimentelle globale NOAA/NCEP-Vorhersage auf Basis des Machine-Learning-Modells GraphCast von Google DeepMind. In GribStream bleibt es als historisches Archiv für Vergleich, Forschung und Backtesting erhalten.

Das Kernmodell ist ein Message-Passing Graph Neural Network mit Encoder-Processor-Decoder-Design. Es wurde mit ERA5 vortrainiert und nutzt in der NOAA-Implementierung zwei GDAS-Analysezustände als Eingabe: den aktuellen Zeitpunkt und den Zustand 6 h davor.

Die verfügbare Konfiguration konzentriert sich auf ein Grid mit 13 Drucklevels und umfasst Temperatur, Windkomponenten, geopotentielle Höhe, spezifische Feuchte, vertikale Geschwindigkeit und Standard-Oberflächenvariablen.

Die historische Abdeckung von graphcast reicht bis zum Lauf 2026-05-05 00:00 UTC. Für aktuelle globale Zyklen auf KI-Basis nutzen Sie AIGFS oder AIGEFS bei NOAA oder AIFS bei ECMWF.

GraphCast ist über seine GDAS-Anfangsbedingungen mit GFS verbunden und lässt sich mit anderen globalen KI-Modellen wie AIGFS und AIFS vergleichen. Es ersetzt numerische Wettervorhersage nicht; nutzen Sie es zusammen mit physikalischen Modellen für historische Validierung, Backtesting und Risikobewertung.
