NOAA AI Global Forecast System Pressure Levels (AIGFS Pressure)

GribStream-Code: aigfspres

Operativer Status: NOAA hat AIGFS v1.0 und AIGEFS v1.0 am 17. Dezember 2025 zusammen mit HGEFS operativ eingeführt. In GribStream sind diese Datasets die aktuelle operative NOAA-Linie für globale KI-basierte Vorhersagen; graphcast bleibt ein historisches experimentelles Archiv.

Technische Referenzen: NOAA EAGLE AWS Open Data Registry, NCEP AIGFS-Produkte, NOMADS-Verteilung, NWS SCN 25-89 und NOAA/NCEP Office Note 521.

Beschreibung

AIGFS Pressure ist das Drucklevel-Produkt des operativen Artificial Intelligence Global Forecast System von NOAA/NCEP. NOAA hat AIGFS v1.0 am 17. Dezember 2025 operativ eingeführt; diese Seite deckt den Höhenanteil von AIGFS neben AIGFS Surface ab.

Das Dataset behält die GraphCast-basierte AIGFS-Logik bei und wird aus der operativen globalen NOAA-Analyse initialisiert. Dadurch können Sie eine deterministische KI-Vorhersage mit globalen physikalischen Modellen vergleichen, ohne das GribStream-Abfragemuster zu ändern.

aigfspres ist die passende Option, wenn Sie die Struktur der Atmosphäre oberhalb der Oberfläche benötigen: Steering Flow (steuernde Strömung), Temperaturprofile, Feuchteschichten, Wellen in mittleren und hohen Levels und vertikale Bewegung.

Das Dataset enthält U/V-Wind, Temperatur, geopotentielle Höhe, spezifische Feuchte und vertikale Geschwindigkeit auf Drucklevels über 13 Standardlevels: 50, 100, 150, 200, 250, 300, 400, 500, 600, 700, 850, 925 und 1000 mb. Es läuft auf einem globalen 0.25-Grad-Grid, mit 00/06/12/18-UTC-Läufen und 6-h-Schritten bis 384 h.

Für GribStream-Kunden ist AIGFS Pressure nützlich für synoptische Analyse, erste Trajektorienbewertung, mittelfristige Dashboards, Vergleiche zwischen KI- und physikalischen Modellen und Produkte, die Drucklevel-Variablen verwenden.
