Abstract:   (2624 Views)

 Fitting a suitable covariance function for the correlation structure of spatial-temporal data requires de-trending the data. In this article, some potential models for spatial-temporal trend are presented. Eventually the best model will be announced for de-trending tropospheric ozone concentration data for the city of Tehran (Capital city of Iran). By using the selected trend model, some features of the covariance function of de-trended data will be specified. 

Keywords: Spatial-temporal random Field, modeling spatial-temporal trend, dynamic spatial linear model, symmetry, separability, ozone concentration
