Aerosol size distributions: remote determination from air-borne measurements of the solar aureole.
Aerosol size distributions were determined remotely using an airborne scanning photometer. This instrument consists of a sunshade, optics, and a large dynamic range photodetector-amplifier system that scans about the vertical, recording both the direct attenuated solar beam and the diffuse sky radiance in the almucantar of the sun at an effective wavelength of 0.54 microm. The inversion of the measured radiances determined aerosol radii from approximately 0.2 microm to 8.0 microm. Data were taken during flights in May 1973 over western Lake Superior and southwestern Wisconsin. Inverted aerosol size distributions are compared with results obtained by other methods.
