a Kernel density estimation. b Scatter plot of model versus observation. Modeled concentrations are fitted to the observed size range according to NSDAM. The colored line represents the line of best fit using an orthogonal regression. The graph refers to 146 data points [MP/m3 or μg/m3]16,20,21,22,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83.
