Abstract
In this paper a class of product-sum covariance models is introduced, in order to estimate and model realizations of space-time random fields, which are very common in environmental applications. Some constraints on the coefficients of this class of models are given in order to guarantee the positive definiteness condition. An overview of some classes of space-time covariance models and a short comparative study is presented; moreover, an application is considered.
