Each record includes the observation date, station identifier with geographic hierarchy, and corresponding pan evaporation values. The dataset is essential for hydrological studies, irrigation planning, agricultural water management, drought assessment, and climate monitoring. It helps analyze evaporation patterns, estimate water loss from surface reservoirs and water bodies, assess crop water requirements, and understand the influence of climatic conditions on water resources across Tamil Nadu.
