Abstract

This work presents the evolution of the levels of atmospheric contaminants measured in the city of Alcoy (Spain) in the stations of the manual network (SO2 and Black smokes) from the year 1989 till 2000; as well as in the stations of the automatic network (SO2, NO2 and suspended particles) between the years 1995 and 2000. The analysis of these data series allow to detect the parallel existing between the two measuring systems and the improvement of the air quality: a significant decrease in the levels of SO2 and Black smokes coinciding with the change from Diesel to natural gas in the heating systems of the region in 1997. At the same time, the analysis of the patterns of daily evolution in the series obtained in the automatic network, together with the topographic characteristics, has allowed to interpret the spatial variations found.
