Effects of Hyperfine Particles on Reflectance Spectra from 0.3 to 25 μm☆

Fine grained particles ,50 mm in size dominate particle size changes in the volume scattering region, the Christiansen feadistributions of many planetary surfaces. Despite the predomi- ture, restrahlen bands, and transparency features. The quartz nance of fine particles in planetary regoliths, there have been particle size series were less well modeled, with the greatest few investigations of the systematic effects of the finest particles discrepancies in the restrahlen bands and the overall spectral on reflectance spectra, and on the ability of quantitative models contrast. © 1997 Academic Press to extract compositional and/or textural information from remote observations. The effects of fine particles that are approximately the same size as the wavelength of light on reflectance
