Fig. 1: Spatial distribution of the atmospheric concentration of microplastic particles.
From: Global atmospheric distribution of microplastics with evidence of low oceanic emissions
a. Horizontal distribution (base case) of mass density (μg/m3) for sub-70 μm microplastic particles in the near-surface layer of the model (altitude of 0–50 km). b Vertical and latitudinal distribution (base case) of zonal mean mass density for sub-70 μm microplastic particles. Similar plots for each size bin are provided in Figs. S2 and S3. c, d Percentage difference in the mass concentrations for particles represented in the base versus the spheres case, for the same conditions as for (a) and (b). The percentage difference is expressed as (base−spheres)/base.
