GribStream

NOAA National Blend of Models - Puerto Rico

Código GribStream: nbmpr

Outras grades NBM: nbm, nbmak, nbmhi, nbmgu, nbmoc

Status do NBM v5: o NBM v5 já está operacional neste dataset. No arquivo do GribStream, 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.

Campos de acumulação como APCP, ASNOW e FICEAC, quando presentes, continuam pela faixa horária ampliada do NBM v5 e depois seguem em /timeseries com períodos de acumulação mais longos, sem lacunas nem janelas duplicadas.

Descrição

NBM Puerto Rico é a saída regional do National Blend of Models para Puerto Rico. Ela leva o pós-processamento operacional da NOAA a uma grade focada nesse domínio, em vez de usar a grade CONUS principal.

O NBM combina várias fontes de previsão e aplica calibração estatística para produzir campos mais consistentes do que os de um modelo individual sem calibração. O objetivo é entregar uma base de previsão mais estável para produtos operacionais e decisões em que o risco meteorológico importa.

O sistema usa técnicas como Model Output Statistics (MOS), Quantile Mapping e ponderação de ensemble. Nos domínios regionais, essa mistura mantém uma orientação local útil sem mudar o jeito de consultar a API.

No GribStream, nbmpr preserva os códigos de variável, níveis e valores de info do catálogo. Você pode usar os mesmos endpoints e seletores dos outros códigos NBM, mudando apenas o código do modelo.
