Abstract

In this article a geostatistical model is presented in order to spatially characterize the PM10 pollutant behavior in the city of Medellin, Colombia. The data has been taken from nine monitoring locations in monthly average value (µg/m3) for the period from January 2003 to December 2007. Different models were evaluated by cross-validation tests. The best model is a j-bessel. The model parameters are calculated using ANOVA tests for quarterly groupings. Maps of the pollutant’s spatial characterization are obtained with ordinary Kriging and GIS.En este artículo se presenta un modelo geoestadístico para caracterizar espacialmente el comportamiento del contaminante PM10 en la ciudad de Medellín Colombia. Los datos se han tomado de nueve sitios de monitoreo en valor promedio mensual (µg/m3) durante el periodo enero 2003 a diciembre 2007. Se evaluaron diferentes modelos mediante pruebas de validación cruzada. El mejor modelo es el j-bessel. Se calculan los parámetros del modelo mediante pruebas ANOVA para agrupaciones trimestrales. Con Kriging ordinario y sistemas de información geográfica, se obtienen mapas de caracterización espacial del contaminante
