BACS: Merged Aerosol Size Distributions

Summary

Best-estimate merged aerosol size distributions over the diameter range of 0.007 to 40 µm (or narrower, depending on instruments used) based on data collected from a combination of scanning mobility particle sizer, optical particle sizer, and aerodynamic particle sizer data during the BACS (BioAerosols and Convective Storms) campaign.
