arXiv:2505. 02979v4 Announce Type: replace-cross Abstract: We propose a novel inverse-modelling approach that estimates the parameters of a simple land-surface model (LSM) by assimilating data into a differentiable, physics-based forward model formulated using convolutional operations.

The paper introduces KAINN, a hybrid neural‑mechanistic model that augments the Agriculture‑informed Neural Network with domain knowledge on fertilizer diffusion, soil respiration, and water‑filled porosity to predict nitrous oxide emissions from agriculture. Experiments across CNN, LSTM, and Transformer architectures show that KAINN achieves lower root mean square error, lower mean absolute error, and higher R-squared values compared to purely data‑driven models and the original AINN. The learned interfaces exhibit smoother, more physically consistent parameter trajectories with reduced uncertainty.

The paper evaluates a physics-informed neural network (PINN) for short‑horizon atmospheric temperature forecasting where observations are sparse. Using ERA5 data at three pressure levels, the PINN outperforms persistence, local‑trend, and two neural‑network baselines, with mean RMSE improvements ranging from 8.1 % at one hour to 23.8 % at three hours. The advantage persists under severe observation sparsity and transfers across regions, though it degrades in complex terrain, highlighting limits of a fixed vertical‑coordinate representation.
