Abstract: Gaussian processes are first choice stochastic models in almost
every applicative field, including geostatistics of climate data.
Covariance functions can be seen as the key ingredients to Gaussian
modeling: finding a suitable Gaussian process for a given application is
equivalent to finding a “good” covariance function.
Alas, not every function is the covariance of a Gaussian process, and
proving that one is can be a hard problem.
In this talk we will focus on covariance functions for spatio-temporal
modeling at the scale of planet Earth, keeping in mind climate data.
We will start with a gentle introduction to the theoretical background and
a quick review of the existing covariances on the sphere, and finish with
some new ideas about anisotropic and seasonal covariances.
