Figures & data
Figure 1. Map of the city of Santiago de Chile with the location of the monitoring sites.
Figure 2. (a) PM2.5 concentration at night and day from 2001 to 2008 in La Florida. (b) PM2.5 concentration at night and day from 2001 to 2008 in Parque O’Higgins. The straight lines are Theil–Sen fits to the data.
Figure 3. Regression analysis from 2001 to 2008 showing the influence of several meteorological variables on PM2.5.
Figure 4. Average black carbon concentration in the rural and urban sites. The inset shows BC in the rural site (Peñaflor).

Figure 5. (a) Particle size distribution in the downtown urban site (Alameda), for three time periods. (b) Size distribution in the urban site south (La Cisterna). (c) Size distribution in the rural site (Peñaflor).
Figure 6. (a) Time series between black carbon and ultrafine particles (10–39 nm) in Alameda. (b) Time series between black carbon and large particles (175–700 nm) in the same place.
Figure 7. Correlation coefficient between black carbon and different groups of particles in the three sites.
Figure 8. (a) Number of ultrafine particles (10–39 nm) in a day with high solar radiation in Peñaflor. (b) Number of particles in a day with low solar radiation in Peñaflor. (c). Number of particles with high solar radiation in the urban site (La Cisterna). (d) Number of particles with low solar radiation in La Cisterna.
Figure 9. Correlation coefficient between the number of ultrafine particles and total solar energy in Peñaflor.
