Il set di dati Ocean Heat Fluxes fa parte del NOAA Ocean Surface Bundle (OSB)
e fornisce un record di dati climatici (CDR) di alta qualità dei flussi di calore aria/oceano
sugli oceani privi di ghiaccio.
Questo set di dati viene calcolato a partire dai parametri CDR OSB della temperatura atmosferica e della superficie del mare vicino alla superficie utilizzando un emulatore di rete neurale dell'algoritmo di flusso aria-mare TOGA-COARE.

Il punto di distribuzione ufficiale dei CDR del programma NOAA CDR è il National Climatic Data Center della NOAA, che fornisce accesso aperto e sostenuto e gestione attiva dei dati dei pacchetti CDR e delle informazioni correlate in linea con le politiche e le pratiche di dati aperti degli Stati Uniti, come descritto nel memorandum del presidente sulla "Open Data Policy" e ai sensi dell'ordine esecutivo del 9 maggio 2013, "Making Open and Machine Readable the New Default for Government Information". In linea con queste norme,
i set di dati CDR non sono proprietari, sono disponibili pubblicamente e non
sono previste restrizioni al loro utilizzo. Per saperne di più, consulta il pdf
