The average calculated mass median diameter (MMD) and geometric standard deviation (GSD) for each aerosol based on the SMPS and APS data.

Aerosol	MMD + Standard deviation (μm)	GSD + Standard deviation
0.9% Salt Solution	0.58±0.04	1.80±0.04
5% Salt Solution	0.81±0.01	1.60±0.08
Arizona Road Dust	2.63±0.09	1.00±0.06
Diesel Fume	Multimodal distribution, two modes* (Figure S2 in Supplemental Information, SI)
Welding Fume	Multimodal distribution two modes* (Figure S3 in Supplemental Information, SI)
