GribStream

NOAA National Blend of Models Parallel - Oceanic

GribStream-Code: nbmparoc

Andere NBM-Parallel-Grids: nbmpar, nbmparak, nbmparhi, nbmparpr, nbmpargu

Status: NBM v5 ist in GribStream jetzt unter nbmoc operativ. In nbmoc 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. Für Produktionsintegrationen mit NBM v5 nutzen Sie nbmoc; die Datasets nbmpar* bleiben für zukünftige experimentelle NBM-Iterationen reserviert, falls NOAA sie wieder über die parallele Linie veröffentlicht.

Der Quell-Bucket ist noaa-nbm-para-pds. GribStream hält die parallele Linie unter eigenen Dataset-Codes, damit Sie sie mit der operativen NBM-Familie vergleichen können, ohne sie mit dem Archiv Ihrer laufenden Integrationen zu vermischen.

Technische Referenzen: PNS 25-45, Winter-v5.0-Konfigurationsnotizen und NBM Versions.

Beschreibung

NBM Parallel Oceanic ist die öffentliche parallele Ausgabe des National Blend of Models für die ozeanische Domain. Sie ist für Vergleich und Validierung gedacht, wenn NOAA eine experimentelle Linie neben der operativen Version veröffentlicht.

Für Produktion mit NBM v5 ist nbmoc das empfohlene Dataset. nbmparoc bleibt als Vergleichsreferenz und als Platz für zukünftige experimentelle Iterationen erhalten, die NOAA in der parallelen Linie veröffentlichen könnte.

NBM v5 war nicht nur eine Parameteraktualisierung. NOAA erweiterte einen großen Teil der stündlichen Vorhersagebasis von 36 h auf 48 h und überarbeitete die Mischung mit mehr Quantile Mapping, Änderungen bei deterministischem Wind und Böen sowie höher aufgelösten ECMWF- und kanadischen Eingaben.

Für die ozeanische Domain nennen die NBM-v5-Notizen probabilistische Wind- und Böenvorhersagen mit Quantile Mapping, aktualisierte Produkte für Temperatur, Taupunkt und Bewölkung sowie eine Korrektur der signifikanten Wellenhöhe, die auf Quantile Mapping und eine deutlich breitere Eingabemodell-Mischung umgestellt wurde.

In GribStream behält nbmparoc stabile Selektoren: Die Werte von name, level und info werden exakt aus dem Katalog kopiert und nicht übersetzt.

Archive window: Last 5 days
Öffentliche Quelle: https://registry.opendata.aws/noaa-nbm-parallel/
Wichtigste Merkmale:
- Ermöglicht den Vergleich der öffentlichen parallelen NBM-Linie mit der operativen Version, wenn NOAA parallele Daten veröffentlicht.
- Die Quelle hält nur eine kurze Retention; diese Linie ist für Validierung gedacht, nicht für Produktion oder ein langfristiges historisches Archiv.
- Nutzt dieselben GribStream-Endpoints wie die operative NBM-Familie, aber unter eigenem Dataset-Code.
- Erhält die Variablencodes, Levels und info-Werte aus dem Katalog von nbmparoc.
Auflösung: Ungefähr 10 km auf dem ozeanischen Grid.
Zeitliche Abdeckung: Stündliche Zyklen; Lead Time (Vorhersagehorizont) von 1 bis 264 h, wenn die Quelle diese Horizonte veröffentlicht. Die parallele Linie bewahrt hauptsächlich die letzten 5 Tage auf.
Hauptanwendungen: Maritime Validierung, Vergleich von Wind, Böen, Bewölkung, Temperatur, Taupunkt und signifikanter Wellenhöhe, Küstenplanung und Prüfung von Integrationen, bevor nur noch NBM Oceanic operativ genutzt wird.
