Researchers have explored the application of Physics-Informed Neural Networks (PINNs) for predicting nitrous oxide (N2O) flux, a significant greenhouse gas. Their study utilized an MLP-based PINN trained on agricultural data from four US sites, drawing upon mechanistic equations from process-based models like DayCent and Cycles. The PINN demonstrated substantial improvement over uncalibrated Cycles simulations, achieving a mean R^2 of 0.411 across ten seeds, though physics constraints sometimes degraded in-distribution accuracy while enhancing out-of-distribution robustness.
