Short summary
We developed the Biogeochemistry-Informed Neural Network (BINN) which embeds a process-based model inside an AI framework so the model’s parameters can be learned from empirical data. BINN could recover prescribed parameters in synthetic tests and retrieve key processes controlling the modeled soil organic carbon when applied to ~25 000 soil profiles in US. It operates more than 50 times faster than the traditional Bayesian approach for data-model integration.
