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. %> http://jsri.srtc.ac.ir/article-1-75-en.pdf %P 177-192 %& 177 %! %9 Research %L A-10-1-51 %+ %G eng %@ 2538-5771 %[ 2012
