Researchers have introduced DIAGNO, a novel Diagonal Spherical Neural Operator designed to model heterogeneous Earth dynamics more accurately. Unlike previous methods that assume rotation equivariance and treat the Earth as homogeneous, DIAGNO explicitly parameterizes cross-modal interactions within the spherical spectrum. This approach better captures the inherent heterogeneity of Earth systems, including atmosphere and ocean dynamics. Experiments show DIAGNO achieves state-of-the-art performance in multi-step forecasting and demonstrates practical value in geophysical domains by accurately capturing anomalies and maintaining physical consistency.
