Details

CHIRTS-ERA5 is a quasi-global (60°S to 70°N), high-resolution (0.05° × 0.05°) dataset of daily maximum and minimum temperatures, heat index, and wet bulb globe temperature from 1980 to near-present.

The dataset combines the Climate Hazards Center Infrared Temperature with Stations (CHIRTS) product (1983–2016) with the regularly updated ERA5 reanalysis. ERA5 fields are downscaled and bias-corrected relative to CHIRTS to provide a temporally consistent climate record.
