Dataset for: A differentiable Xinanjiang model with multi-layer soil moisture state correction for runoff simulation

This dataset supports the manuscript "A differentiable Xinanjiang model with multi-layer soil moisture state correction for runoff simulation". The dataset contains public input data, model evaluation metrics, and public model-output files for the Daning River basin and ten CAMELS-US basins. It includes processed CAMELS-US forcing, public CAMELS-US runoff observations, prepared soil moisture inputs, model performance metrics, simulated runoff, model parameters, and state-correction diagnostics. Daily observed runoff and station precipitation for the Daning River basin are not included because they are subject to data-provider restrictions. Source code, neural-network weight files, training logs, and intermediate optimization databases are also not included.
