Abstract: | The small number of ground stations for the assessment of the spatial distribution of air pollutants motivates the search
for methods that make use of satellite images. One such method, known as Differential Texture Analysis (DTA), is used to measure
the Aerosol Optical Thickness in the Visible (AOTV), which correlates highly with air quality. With this method, the presence
of clouds and/or land cover changes produce patches of missing values. In this paper we demonstrate that universal kriging
can be used to obtain reasonable estimates for these missing values. The methodology was applied to a satellite derived AOTV
map of the city of Brescia (Italy).
