Physics-informed neural networks simulate pollution spread under thermal inversion

Researchers have developed a robust Physics-Informed Neural Network (PINN) framework to simulate time-dependent pollution propagation, particularly under thermal inversion conditions. This new framework incorporates a robust variational approach and a collocation-based strategy to enhance training speed and accuracy. The model was tested in Longyearbyen, Spitsbergen, using snowmobile traffic as a case study, revealing how thermal inversions trap pollutants near the ground, leading to significantly worsened air quality.
