El Sistema de Previsión Climática (CFS) de los Centros Nacionales de Predicción Ambiental (NCEP) es un modelo completamente acoplado que representa la interacción entre la atmósfera, los océanos, la tierra y el hielo marino de la Tierra. El CFS se desarrolló en el Centro de Modelado Ambiental (EMC) del NCEP. El CFS operativo se actualizó a la versión 2 (CFSv2) el 30 de marzo de 2011.
Las previsiones se inicializan cuatro veces al día (0000, 0600, 1200 y 1800 UTC). Este es el mismo modelo que se usó para crear el reanálisis del Sistema de Pronóstico Climático (CFSR) del NCEP, y el propósito del conjunto de datos de CFSv2 es extender el CFSR. Solo transferimos un subconjunto de bandas de los archivos que coinciden con cdas1.t??z.sfluxgrbf06.grib2.
