  1. Particle size, modal spread (δ), and ĸ for fitted number—size distribution peaks shown on left. Fitted particle volume peaks and spread shown on right. Dashed lines represent the lack of more peaks in the volumetric distributions. Missing ĸ-values indicate that lognormally fitted peak diameters were outside of sizes resolved by the CCNC.
