What is recorded here?
Uses spherical-harmonic convolutions rather than planar FFTs for operator learning on spherical geometry, with a differentiable spherical-harmonic implementation and reported stable atmospheric rollouts.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Seven original authors. SO(3) equivariance pertains to the specified linear spherical layer/continuous construction; discrete nonlinearities are only approximate and the proposed nonlinear frequency variant is not equivariant. Position embeddings and valid transforms constrain grid transfer. Year-long plausible rollouts do not establish climate fidelity or long-horizon trajectory accuracy.
