Status: o NBM v5 já está operacional no GribStream em nbmoc. Em nbmoc, execuções anteriores a 2026-05-05 12:00 UTC contêm a versão operacional anterior do NBM; execuções a partir de 2026-05-05 12:00 UTC usam o NBM v5. Para integrações de produção com NBM v5, use nbmoc; os datasets nbmpar* ficam reservados para futuras iterações experimentais do NBM se a NOAA voltar a publicá-las na linha paralela.

A fonte pública é noaa-nbm-para-pds. O GribStream mantém a linha paralela em códigos dedicados para você compará-la com a família operacional do NBM sem misturá-la ao arquivo usado pelas suas integrações atuais.

Descrição

NBM Parallel Oceanic é a saída pública paralela do National Blend of Models para a grade oceânica. Ela serve para comparação e validação quando a NOAA publica uma linha experimental ao lado da versão operacional.

Para produção com NBM v5, o dataset recomendado é nbmoc. nbmparoc fica como referência de comparação e como espaço para futuras iterações experimentais que a NOAA possa publicar na linha paralela.

O NBM v5 não foi apenas uma atualização de parâmetros. A NOAA ampliou grande parte da base horária de previsão de 36 h para 48 h e revisou a mistura com mais Quantile Mapping, mudanças em vento e rajadas determinísticas, e entradas de maior resolução do ECMWF e do Canadá.

Para o domínio oceânico, as notas do NBM v5 destacam orientação probabilística de vento e rajadas corrigida por Quantile Mapping, produtos atualizados de temperatura, ponto de orvalho e nebulosidade, e uma correção de altura significativa de onda que passa a usar Quantile Mapping com um conjunto muito mais amplo de fontes de entrada.

No GribStream, nbmparoc mantém seletores estáveis: os valores de name, level e info são copiados exatamente do catálogo e não são traduzidos.
