New methods of constraining aerosol properties through the inversion of multi-angle, multi-spectral and polarimetric observations are developed. Specifically, this research utilizes a wide range of radiative measurements across the shortwave solar spectrum to derive properties of atmospheric particulate, including aerosol optical depth, single scattering albedo (i.e. absorption), size distribution, particle morphology, refractive index and chemical composition. Emphasis is placed on datasets with high information content, especially those stemming from next generation polarimeters possessing wide angular and spectral coverage as well as high polarimetric accuracy. Of particular interest are inversion techniques that fuse polarimetric observations with other measurements obtained through geostationary imagers and/or lidar. A wide range of in situ and remote sensing observation strategies are relevant, including those made from both space-based and suborbital platforms. Inversions of complex optical datasets (e.g. polar nephelometer measurements) obtained in situ aboard aircraft or in the laboratory are particularly pertinent.
