Researchers have developed a physics-informed feature engineering approach for 1D-CNN models to improve multilayer cloud detection from geostationary satellites. This method embeds channel selections derived from threshold-based algorithms as feature-engineering priors into the 1D-CNN, enabling machine learning to learn latent physical relationships for simplified physical retrievals. The enhanced 1D-CNN achieved a probability of detection (PODmul) of 0.620 and a false alarm rate (FARmul) of 0.240, surpassing the conventional threshold algorithm's performance. The study highlights the effectiveness of incorporating prior physical knowledge from radiative transfer theory and suggests that ML-revealed physical mechanisms can also boost traditional algorithms, though sensor-specific characteristics are crucial for operational deployment.
