Researchers have developed a novel contrastive learning model to better understand the sensitivities of physics parameters in climate simulations. This model maps monthly cloud and radiation fields into a shared representation space, achieving over 94% accuracy in distinguishing between two different parameter ensembles for the Community Atmosphere Model version 6 (CAM6). The approach effectively preserves seasonal variability and ensemble spread, and shows that a neural network emulator for microphysics (TAU-ML) performs better in representing satellite observations compared to the default scheme (KK2000). Integrated Gradients attributions pinpoint key regions and parameters, such as cloud microphysics and convection, that influence model differences and observations. AI
