    • Simulation of Stationary Gaussian Random Fields with a Gneiting Spatio-Temporal Covariance 
      Allard, Denis; Emery, Xavier Mathieu; Lacaux, Céline; Lantuéjoul, Christian (Springer, 2023)
      The nonseparable Gneiting covariance has become a standard to model spatio-temporal random fields. Its definition relies on a completely monotone function associated with the spatial structure and a conditionally negative ...
    • Spectral Simulation of Gaussian Vector Random Fields on the Sphere 
      Alegría, Alfredo; Emery, Xavier Mathieu; Freulon, Xavier; Lantuéjoul, Christian; Porcu, Emilio; Renard, Didier (Springer, 2023)
      Isotropic Gaussian random fields on the sphere are used in astronomy, geophysics, oceanography, climatology and remote sensing applications. However, to date, there is a lack of simulation algorithms that reproduce the ...
