Data underlying the publication: The annual dynamic dataset of high-resolution crop water use in China from 1991 to 2019

Here, we produced annual blue and green water use for 15 main crops with a resolution of 1 km in China.Initially, we estimated the daily crop blue and green water use at site scale by incorporating more localized input parameters using dynamic water balance model. Subsequently, we developed a spatial prediction of crop water requirements based on random forest model. The resulting maps showed high correlation with locally observed values at field stations, statistics, and exhibited some strengths compared with existing datasets that covering various scales.
