Pollen transport in a region R inside the university campus showing grains-trees detachment due to the wind-tree-leaves interactions. (a) t = 1 s; (b) t = 2 s; (c) t = 3 s. Computational case of the weather conditions on 06/04/2020 with a total initial number of pollen grains \(n_{max}\approx 0.4\times 10^6\). A local region R of the whole domain corresponds to a box of dimensions: \(L=W=100\) m and \(H=40\) m (see “Methods” section). For the complete aerodynamics at all time steps, see the multimedia video file: Video 4.
