Description

This dataset provides a gridded analysis of daily surface air temperature over global land areas, including daily maximum (Tmax), minimum (Tmin) temperatures. Spanning from 1979 to the present, the data is presented on 0.5-degree latitude/longitude grids, aligning with the resolution of CPC's gauge-based global daily precipitation analysis. The construction of this dataset considers orographic effects. Its primary purpose is to support climate monitoring and forecast verification activities. Input data originates from the CPC archive of GTS (Global Telecommunication System) daily reports, incorporating Tmax and Tmin data from approximately 6,000 to 7,000 global stations.
