Calculation of daily exposure and population-weighted
concentration
Based on the GIS, PM
concentration data from the
seven monitoring stations were spatially interpolated,
using kriging spatial interpolation. PM
10
concentrations
were calculated at resolution 0.01° × 0.01°, approximately
10
1 km× 1 km. Population data were also spatially interpolated,
to attain the high spatial resolution (0.01° × 0.01°)
matching that of PM
concentration data. Using the
GIS spatial information analysis function, the population
and PM

concentration layers (total of 475 grid points)
