GribStream

Climate Forecast System Isentropic Potential Vorticity Fields

Código GribStream: cfsipvf

Descrição

CFS ipvf expõe campos especializados do Climate Forecast System ligados a vorticidade potencial e estrutura isentrópica.

Ele é mais útil para diagnóstico dinâmico e pesquisa do que para produtos finais de usuário comum. Use quando seu workflow precisa de variáveis atmosféricas de larga escala além de temperatura, vento ou precipitação.

No GribStream, cfsipvf mantém os seletores técnicos do catálogo, permitindo consultas pontuais ou em grade sem processar arquivos completos.

Para campos mais gerais da família CFS, consulte cfspgbf e cfsflxf.
