Figure 9From: Are associations between socio-economic characteristics and exposure to air pollution a question of study area size? An example from Scania, SwedenValidation of the concentration model. Modelled annual average concentration of NO2 (μg/m3) versus measured. The modelled concentration is plotted against measured concentration of the annual mean of NO2 from 23 measuring stations in Scania. y = 1.041x - 0.0605 R2 = 0.69Back to article page
