Title: Some models for spatial-temporal processes on the globe
Abstract: Many environmental applications these days involve data on a global scale and such data pose various challenges methodologically and computationally. In this talk, I will discuss several statistical issues regarding spatial-temporal data on the globe, and introduce statistcal models for them. Issues, regarding positive definiteness of functions on the surface of a sphere, covariance functions for smooth processes on the surface of a sphere, nonstationary covariance models for processes on the surface of a sphere, and computational methods for dealing with large data sets, will be discussed. I will give examples of the application of the proposed models to climate problems.
