  "description": "CHIRTS-ER5 daily provides global, high-resolution (0.05°) daily maximum and minimum 2-meter air temperature estimates from 1983 to present. It blends ERA5 reanalysis with station observations using the CHIRTS algorithm, producing a consistent long-term record suitable for climate trend analysis, heat-stress monitoring, and agricultural modeling.",
