Abstract

A camera has been developed to image the sun and the solar aureole for use in aerosol studies. The design and calibration of the system are presented in a companion paper. The camera has eight spectral channels in the wavelength range from 310 nm to 1045 nm. The spectral bands and data collection procedure are chosen to allow retrieval of the atmospheric aerosol size distribution, index of refraction, and scattering phase function. In addition, the camera provides data for the retrieval of the atmospheric water vapor and ozone. The aerosol size distribution retrieval is based on the combined inversion of solar extinction and solar aureole data. The real part of the aerosol refractive index is determined using scattering measurements in the near-backward direction, while diffuse-to-global measurements provide the imaginary part. The performance of the inversion schemes is illustrated for in-flight satellite signal predictions over both bright and dark targets.
