Spherical Harmonic Optimal Transport: Application to Climate Models Comparisons
Researchers have developed a new method called Spherical Harmonic Optimal Transport (SHOT) to make comparing complex datasets more computationally efficient. This technique adapts optimal transport algorithms for use on spherical manifolds, specifically the 2-sphere, by leveraging heat kernel properties and harmonic structures. The SHOT method significantly reduces memory and time requirements, making it practical for applications like evaluating global climate models and offering detailed spatial and seasonal performance insights.
