Abstract
In this paper we explore a covariance spectral modelling strategy for spatial-temporal processes which involves a spectral approach for time but a covariance approach for space.It facilitates the analysis of coherence between the temporal frequency components at different spatial sites. Stein(2005) developed a semi-parametric model within this framework.The purpose of this paper is to give a deeper insight into the properties of his model and to develop simple and more intuitive methods of estimation and testing. An example is given using the Irish wind speed data.
