Cet ensemble de données fournit une analyse maillée de la température de l'air en surface au quotidien sur les zones terrestres du monde entier, y compris les températures maximales (Tmax) et minimales (Tmin) quotidiennes. S'étendant de 1979 à aujourd'hui, les données sont présentées sur des grilles de latitude/longitude de 0,5 degré, ce qui correspond à la résolution de l'analyse mondiale quotidienne des précipitations basée sur les jauges du CPC. La construction de cet ensemble de données tient compte des effets orographiques. Son objectif principal est de soutenir les activités de surveillance du climat et de validation des prévisions. Les données d'entrée proviennent des rapports quotidiens de l'archive CPC du GTS (Global Telecommunication System), qui intègrent les données Tmax et Tmin d'environ 6 000 à 7 000 stations mondiales.
