Das Climate Forecast System (CFS) der National Centers for Environmental Prediction (NCEP) ist ein vollständig gekoppeltes Modell, das die Interaktion zwischen der Erdatmosphäre, den Ozeanen, dem Land und dem Meereis darstellt. CFS wurde im Environmental Modeling Center (EMC) des NCEP entwickelt. Das operative CFS wurde am 30. März 2011 auf Version 2 (CFSv2) aktualisiert.
Prognosen werden viermal täglich initialisiert (0000, 0600, 1200 und 1800 UTC). Es ist dasselbe Modell, das zum Erstellen der NCEP Climate Forecast System Reanalysis (CFSR) verwendet wurde. Das CFSv2-Dataset soll CFSR erweitern. Wir erfassen nur eine Teilmenge von Bändern aus Dateien, die dem Muster cdas1.t??z.sfluxgrbf06.grib2 entsprechen.
