Abstract A fully automated aerosol particle size spectrometer system is described that consists of a light scattering particle sensor, an analog to digital converter, and a microcomputer with associated printout device. The system is capable of acquiring a differential particle size distribution, printing the resulting spectrum in one of three representations, and repeating the procedure at preselected intervals. An example of the application of the system for measuring an outdoor aerosol size distribution is presented. The appendices contain documented microcomputer program listings and flow charts for Program Sizer (the program that operates the spectrometer system and the principal result of this study) and Program MCA (a program that converts part of the spectrometer system to a conventional 256-channel pulse height analyzer).
