Emery, Xavier; Alegría, Alfredo (Springer, 2020)An extension of the turning arcs algorithm is proposed for simulating a random field on the two-dimensional sphere with a second-order dependency structure associated with a locally varying Schoenberg sequence. In particular, ...

Alegría, Alfredo; Emery, Xavier; Lantuéjoul, Christian (Springer, 2020)Random fields on the sphere play a fundamental role in the natural sciences. This paper presents a simulation algorithm parenthetical to the spectral turning bands method used in Euclidean spaces, for simulating scalar- ...
