NBM-v5-Status: NBM v5 ist in diesem Dataset jetzt operativ. Im GribStream-Archiv enthalten Läufe vor 2026-05-05 12:00 UTC die vorherige operative NBM-Version; Läufe ab 2026-05-05 12:00 UTC verwenden NBM v5.
Akkumulationsfelder wie APCP, ASNOW und FICEAC laufen, sofern sie vorhanden sind, durch den erweiterten stündlichen Bereich von NBM v5 und gehen danach in /timeseries mit längeren Akkumulationsperioden weiter, ohne Lücken oder doppelte Zeitfenster.
NBM Oceanic ist die regionale Ausgabe des National Blend of Models für die ozeanische Domain. Sie bringt NOAAs operatives Postprocessing auf ein Grid, das auf diese Domain zugeschnitten ist, statt die CONUS-Hauptdomain zu verwenden.
NBM kombiniert mehrere Vorhersagequellen und kalibriert sie statistisch, um konsistentere Felder zu erzeugen als ein einzelnes unkalibriertes Modell. Der Zweck ist eine stabilere Vorhersagebasis für operative Produkte und Entscheidungen, bei denen Wetterrisiko zählt.
Das System nutzt Techniken wie Model Output Statistics (MOS), Quantile Mapping und Ensemble-Gewichtung. In den regionalen Domains bleibt der API-Workflow gleich: Sie wählen das regionale NBM-Dataset und verwenden die Katalogselektoren wie bei anderen NBM-Codes.
In GribStream behält nbmoc die Variablencodes, Levels und info-Werte des Katalogs. Sie können dieselben Endpoints und Selector-Muster verwenden und nur den Modellcode wechseln.
