Questo set di dati fornisce un'analisi a griglia della temperatura dell'aria superficiale giornaliera
sulle aree terrestri globali, comprese le temperature giornaliere massima (Tmax) e minima (Tmin). I dati, che vanno dal 1979 a oggi, sono presentati su
griglie di latitudine/longitudine di 0,5 gradi, in linea con la risoluzione dell'analisi
delle precipitazioni giornaliere globali basata sui dati dei pluviometri del CPC. La costruzione di questo
set di dati tiene conto degli effetti orografici. Il suo scopo principale è supportare
le attività di monitoraggio del clima e di verifica delle previsioni. I dati di input provengono dall'archivio CPC dei report giornalieri del GTS (Global Telecommunication System), che incorporano i dati Tmax e Tmin di circa 6000-7000 stazioni globali.
I set di dati NOAA CPC sono disponibili senza restrizioni
sull'utilizzo o la distribuzione. NOAA PSL richiede che l'utente
attribuisca correttamente i dati e identifichi NOAA PSL, ove applicabile,
come origine dei dati.
