Field:

Standard deviation of population

Description:Standard deviation of population within a 50 km radius from the site based on GPW3 2.5' (arc-minutes) population data. Large variations within the population pattern around a site might introduce large differences in the pollutant levels depending on wind direction. Measurements at sites with small standard deviation of population in the surroundings are therefore thought to be more representative of a larger domain and the mean population density.
