A Balloon-Borne Aerosol Counter
Abstract
A balloon-borne aerosol counter which samples and sizes individual particles to an accuracy of plus or minus 10 percent over an order of magnitude size range extending down to 0.1 - 0.2 micron diameter regime, has been successfully flown. The device is completely self-contained and recoverable. The data are recorded on 9-channel magnetic tape in digital format compatible with an IBM 360 computer, and are processed automatically. Stratospheric aerosol size distributions have been obtained in increments of one and two kilometers, up to and including balloon float altitudes (above 23 km). These represent the first such direct information available, and are presented here in preliminary form. A description of the device, together with a discussion of calibration and automatic data reduction procedures, as well as recommendations for improvements in the latter, is given.
