Measured TSP (µg/m

Fig. 2.
Comparison between the measured and the modeled data. On the X-axis: the measured
pollutant concentratins. On the Y-axis: the modeled pollutant concentrations. Each color
represents a different station, for which the line of the same color represents the regression of the
modeled concentrations on the measurements. In the left column of figures, the plots for SO
2
are
shown. In the right column, those for TSP (measurements)/PM10 (modeled) are shown. Above:
the results for January 2004. Below: the results for October 2004. Each point represents 1 day for
which both measurements and model data were available
