Abstract
This MATLAB scripts is used to plot Fig. 4 of Huang et al. (2020), in review. This scripts first uses Monte-Carlo method to sample a large number (10^8) of volume-equivalent dust particles from the globally-averaged shape distributions of AR and HWR (compiled in Supplementary Tables S2 and S3 of Huang et al., 2020). Second, for each of these generated particles, we used Eqs. (5) - (7) and Eq. (4), respectively, to obtain its the gravitational settling speed and that of its volume-equivalent spherical dust. Finally, for each dust particle, we calculated the reduction in terminal velocity and the enhancement of lifetime due to dust asphericity.
