From: Risk assessment of pollen allergy in urban environments
Effect of weather conditions and urban infrastructure on airborne pollen aerodynamics outdoors in a university campus. Computational results at \(t=6\) min are shown from a top-view 3D perspective. (a) 06/04/2020 (yellow-colored grains); (b) 07/04/2020 (red-colored grains); (c) 08/04/2020 (blue-colored grains); (d) 09/04/2020 (magenta-colored grains); (e) 10/04/2020 (cyan-colored grains); see Table 1. The initial number of pollen grains, in this case, is \(n_{max}\approx 0.4\times 10^6\). For the complete aerodynamics at all time steps, see the multimedia video files: Video 1, Video 2 and Video 3.
