GribStream

NOAA National Blend of Models Parallel - Oceanic

Codice GribStream: nbmparoc

NBM 2 meter temperature across its complete oceanic product grid with black boundaries
NBM 2 m temperature across the complete populated footprint at the 10 km spacing used by the oceanic product family, with black boundaries. This coverage reference was generated from nbm for the nbmparoc page; available variables may differ.

Altre griglie NBM Parallel: nbmpar, nbmparak, nbmparhi, nbmparpr, nbmpargu

Status: NBM v5 è già operativo in GribStream in nbmoc. In nbmoc, i run precedenti a 2026-05-05 12:00 UTC contengono la versione operativa precedente di NBM; i run da 2026-05-05 12:00 UTC in poi usano NBM v5. Per integrazioni di produzione con NBM v5 usa nbmoc; i dataset nbmpar* restano riservati a future iterazioni sperimentali di NBM se NOAA torna a pubblicarle nella linea parallela.

La fonte pubblica è noaa-nbm-para-pds. GribStream mantiene la linea parallela in codici dedicati, così puoi confrontarla con la famiglia NBM operativa senza mescolarla con l'archivio usato dalle integrazioni correnti.

Riferimenti tecnici: PNS 25-45, note di configurazione Winter v5.0 e NBM Versions.

Descrizione

NBM Parallel Oceanic è il prodotto pubblico parallelo del National Blend of Models per la griglia oceanica. Serve a confronto e validazione quando NOAA pubblica una linea sperimentale accanto alla versione operativa.

Per produzione con NBM v5, il dataset consigliato è nbmoc. nbmparoc resta come riferimento di confronto e come spazio per future iterazioni sperimentali che NOAA potrebbe pubblicare nella linea parallela.

NBM v5 non è stato solo un aggiornamento di parametri. NOAA ha esteso gran parte della previsione oraria di base da 36 h a 48 h e ha rivisto il blend con più Quantile Mapping, modifiche a vento e raffiche deterministiche, e input a risoluzione più alta da ECMWF e Canada.

Per il dominio oceanico, le note NBM v5 evidenziano vento e raffiche probabilistiche corretti con Quantile Mapping, prodotti aggiornati di temperatura, punto di rugiada e nuvolosità, e una correzione dell'altezza significativa dell'onda che usa Quantile Mapping con un insieme molto più ampio di fonti in ingresso.

In GribStream, nbmparoc mantiene selettori stabili: i valori di name, level e info vengono copiati esattamente dal catalogo e non sono tradotti.
