Fast generation of isotropic Gaussian random fields on the sphere

Random fields indexed over the sphere are extremely well studied in Probability and Spatial Statistics, because of their strong connection with CMB (Cosmic Microwave

Isotropic Gaussian random fields on the sphere are characterized by Kar-hunen–Loève expansions with respect to the spherical harmonic functions and the angular power spectrum.

a sphere (Porcu et al.,2018), the characterization and modeling of their spatial covariance are more relevant, and require treating such data as realizations of random fields on the sphere.

The efficient simulation of isotropic Gaussian random fields on the unit sphere is a task encountered frequently in numerical applications. A fast algorithm based on Markov

ISOTROPIC GAUSSIAN RANDOM FIELDS ON THE SPHERE: REGULARITY, FAST SIMULATION AND STOCHASTIC PARTIAL DIFFERENTIAL EQUATIONS By Annika Lang1

Consider a random scalar field \ (f (\theta ,\lambda )\) on the sphere, with \ (\theta \) and \ (\lambda \), respectively, denoting colatitude and longitude. For any rotation R around

Stationary and Isotropic Vector Random Fields on Spheres

We review the Dudley integral for the Belyaev dichotomy applied to Gaussian processes on spheres, and discuss the approximate (or restricted) continuity of paths in the

Papers [14, 13] develop the approach to construct time dependent random fields on the sphere through coordinate-change and subordination.These models of random fields arise as

One interesting area of study is the behavior of Random Fields on the sphere, which are used to represent various natural phenomena. This report dives into the temporal

In this paper we define (empirical) quadratic variations for a Gaussian isotropic random field f on the unit sphere as sums over equidistant increments on one single geodesic line on the surface

The individual particles are realizations of isotropic Gaussian random fields on the sphere. We use Gaussian random fields as they provide enormous flexibility in modeling
