Short summary
Understanding how water moves from land to the atmosphere is essential for studying climate and water resources. However, ground observations in China are often incomplete and short. We created the first seamless half-hourly dataset covering China from 2000 to 2024 by carefully filling data gaps and extending observations in time. The dataset closely matches measurements and provides a reliable foundation for climate, water, and environmental research.
