국립 환경 예측 센터 (NCEP) 기후 예측 시스템 (CFS)은 지구의 대기, 해양, 육지, 해빙 간의 상호작용을 나타내는 완전 결합 모델입니다. CFS는 NCEP의 환경 모델링 센터 (EMC)에서 개발되었습니다. 운영 CFS는 2011년 3월 30일에 버전 2 (CFSv2)로 업그레이드되었습니다.
예보는 하루에 네 번 (0000, 0600, 1200, 1800 UTC) 초기화됩니다. 이 모델은 NCEP 기후 예측 시스템 재분석 (CFSR)을 만드는 데 사용된 모델과 동일하며 CFSv2 데이터 세트의 목적은 CFSR을 확장하는 것입니다. cdas1.t??z.sfluxgrbf06.grib2와 일치하는 파일에서 일부 밴드만 인제스트합니다.
