O Sistema de Previsão Climática (CFS, na sigla em inglês) dos Centros Nacionais de Previsão Ambiental (NCEP, na sigla em inglês) é um modelo totalmente acoplado que representa a interação entre a atmosfera, os oceanos, a terra e o gelo marinho da Terra. O CFS foi desenvolvido no Environmental Modeling Center (EMC) do NCEP. O CFS operacional foi atualizado para a versão 2 (CFSv2) em 30 de março de 2011.
As previsões são inicializadas quatro vezes por dia (0000, 0600, 1200 e 1800 UTC). Esse é o mesmo modelo usado para criar a reanálise do sistema de previsão climática (CFSR, na sigla em inglês) do NCEP, e o objetivo do conjunto de dados do CFSv2 é estender o CFSR. Ingerimos apenas um subconjunto de bandas de arquivos que correspondem a cdas1.t??z.sfluxgrbf06.grib2.
