Description
We propose to utilize laboratory-derived photometric data to address a number of problems important to the planetary community. All data are derived from the bloomsburg university goniometer (BUG) lab. This facility is capable of rapidly measuring the full bidirectional reflectance distribution function (BRDF) of laboratory samples in wavelengths between 400-900 NM, and at phase angles of 3-150 degrees in and out of the principal plane. The specific problems we will address in this proposal are the following. (1) how well do traditional photometric models (e.g. hapke, lunar-lambert, minnaert, etc) fit laboratory data? Are there other options for rapid and accurate fits to observed brdfs? (2) what causes the phenomenon known as phase reddening? Can we quantify and predict this behavior? Related to this question, can we quantify and predict variations in absorption band depth with phase angle? (3) how does the opposition surge vary from sample to sample? Given observations with controls on particle size and single-scattering albedo, can we improve the understanding of possible mechanisms for this phenomenon? (4) we have observed an apparent asymmetry in the opposition surge, one not predicted by theory. Is this observation real or an artifact? If real, what causes IT? Can we exploit IT to learn something about a surface regolith? (5) we and others have observed changes in the BRDF and opposition surge that occur when a sample is packed at different bulk densities. How are these changes related to the filling factor? Can we quantify and predict the behavior of a packed regolith given its BRDF in a loose state and vice-versa?
