Mass distribution function for 0.1 μm monomers in the nominal case. Mass distribution functions at times when the system becomes drift limited (drift), bouncing dominated (bouncing), and when the aggregates reach St_min (SI) are plotted. Numbers next to the labels show the times in orbital periods. Vertical lines mark the peak of the distribution function, and the hatched area highlights the region around the peak that contributes 95% to the peak. The mdf show that the system becomes bouncing dominated for 0.1 μm sized monomers. The peak between drift and bouncing changes by ≲ 2%, and the two mdf differ by ≲ 5% around the peak where most of the mass is contained. The larger uncertainties at the low-mass and high-mass ends of the mdf are due to the low resolution of the representative particle method in this part.
