ECMWF IFS em uma grade global de 0.1°. Esta distribuição mais fina usa a mesma previsão dos produtos de 0.25° e chega cerca de duas horas depois.

Os produtos atmosféricos incluem os campos de superfície publicados e todos os níveis de pressão. Os produtos de ondas oferecem previsões marinhas. O inventário abaixo apresenta os seletores exatos. Acumulados, taxas e extremos mantêm as definições e unidades originais.

Quatro ciclos diários: 00, 06, 12 e 18 UTC. O primeiro ciclo das 06 UTC contém passos de três horas de +0 a +144h. Para 00/12 UTC, o ECMWF especifica passos de três horas até +144h e de seis horas de +150 a +360h. O ciclo indica a inicialização, não a publicação.

Os dados de origem a 0.1° começam em 20 de outubro de 2026 às 06 UTC. O histórico IFS anterior permanece nos datasets separados de 0.25°. A disponibilidade depende dos arquivos indexados ainda acessíveis na fonte.

Use os seletores exatos com runs e timeseries. Os ensembles contêm os membros 1–50; o controle está no dataset determinístico correspondente. Os valores ausentes são preservados.
